It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC to any special C compiler that is needed for +# multi-threaded programs (defaults to the value of CC otherwise). (This +# is necessary on AIX to use the special cc_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also to link with them as well. For example, you might link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threaded programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to +# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository. We are also +# grateful for the helpful feedback of numerous users. +# +# Updated for Autoconf 2.68 by Daniel Richard G. +# +# LICENSE +# +# Copyright (c) 2008 Steven G.

The most +fundamental tuning issue for TCP is the TCP window size, which controls how much +data can be in the network at any one point.

The theoretical value to use for the +TCP window size is the <I>bandwidth delay product</I>, +<BLOCKQUOTE>bottleneck bandwidth * round trip time</BLOCKQUOTE>In the below +modi4/cyclops example, the bottleneck link is a 45 Mbit/sec DS3 link and the +round trip time measured with ping is 42 ms.

In our +example, buffer sizes over 130K did not improve the performance, despite the +bandwidth delay product of 230K. +<P>Note that many OSes and hosts have upper limits on the TCP window size. These +may be as low as 64 KB, or as high as several MB. Iperf tries to detect when +these occur and give a warning that the actual and requested window sizes are +not equal (as below, though that is due to rounding in IRIX).

It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC to any special C compiler that is needed for +# multi-threaded programs (defaults to the value of CC otherwise). (This +# is necessary on AIX to use the special cc_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also to link with them as well. For example, you might link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threaded programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to +# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository.

The performance +metrics supported include throughput and latency (or link capacity and responsiveness.) Latency measurements include +both one way delay (OWD) and round trip times (RTTs.) Iperf can use both TCP and UDP sockets (or +protocols.) It supports unidirectional, full duplex (same socket) and bidirectional traffic, and supports +multiple, simultaneous traffic streams. It supports multicast traffic including source specific +multicast (SSM) joins. Its multi-threaded design allows for peak performance. Metrics displayed help to +characterize host to host network performance. Setting the enhanced (-e) option provides all +available metrics. Note: the metrics are at the socket level reads and writes. They do +not include the overhead associated with lower level protocol layer headers. +.LP +The user must establish both a server (to receive traffic) +and a client (to generate and send traffic) for a test to occur. +The client and server typically are on different hosts or +computers but need not be. +.SH "GENERAL OPTIONS" +.TP +.BR -b ", " --bandwidth " " +set the target bandwidth and optional standard deviation per +\fI<mean>\fR,\fI[<stdev>]\fR (See NOTES for suffixes) +.TP +.BR -e ", " --enhanced " " +Display enhanced output in reports otherwise use legacy report (ver +2.0.5) formatting (see NOTES) +.TP +.BR -f ", " --format " " [abkmgBKMG] +format to report: adaptive, bits, Bytes, Kbits, Mbits, Gbits, KBytes, +MBytes, GBytes (see NOTES for more) +.TP +.BR -h ", " --help " " +print a help synopsis +.TP +.BR " --hide-ips " +obscure ip addresses in output (useful when wanting to publish results and not display the full ip addresses. v4 only) +.TP +.BR -i ", " --interval " < \fIt\fR | f >" +sample or display interval reports every \fIt\fR seconds (default) or every frame or burst, i.e. if f is used then the interval will be each frame or burst.

Also note that using --trip-times on a TCP client +will cause --tcp-write-prefetch to be set to a small value if tcp-write-prefetch hasn't hasn't also been set. This is +done to reduce send side bloat latency (which is unrelated to network induced latency.) Set --tcp-write-prefetch +to zero to disable this (which will disable TCP_NOTSENT_LOWAT) and will allow for send side bloat. +.P +.B Synchronized clocks: +The --trip-times option indicates that the client's and server's clocks are synchronized to a common reference. +Network Time Protocol (NTP) or Precision Time Protocol (PTP) are commonly used for +this.

Binding at the +device (or layer 2) level requires the percent (%) as the delimiter (for both the client and the server.) +An example for src port and ip address is -B 192.168.1.1:6001. To \fBbind the src port only\fR and +let the operating system choose the source ip address use 0.0.0.0, e.g. +\fB-B 0.0.0.0:6001\fR. On the client, the -B option affects the \fBbind\fR(2) +system call, and will set the source ip address and the source port, e.g. iperf -c <host> +-B 192.168.100.2:6002. This controls the packet's source values but not routing. +These can be confusing in that a route or device lookup may not +be that of the device with the configured source IP. +So, for example, if the IP address of eth0 is used for -B and the +routing table for the destination IP address resolves +the output interface to be eth1, then the host will send the packet +out device eth1 while using the source IP address of eth0 in the packet. +To affect the physical output interface (e.g. dual homed systems) either use +-c <host>%<dev> (requires root) which bypasses this host route table lookup, +or configure policy routing per each -B source address and set the +output interface appropriately in the policy routes. On the server or receive, +only packets destined to -B IP address will be received. It's also useful +for multicast. For example, iperf -s -B 224.0.0.1\fB%eth0\fR +will only accept ip multicast packets with dest ip 224.0.0.1 that are +received on the eth0 interface, while iperf -s -B 224.0.0.1 will +receive those packets on any interface, +Finally, the device specifier is required for v6 link-local, +e.g. -c [v6addr]%<dev> -V, to select the output interface. +.P +.B Reverse, full-duplex, dualtest (-d) and tradeoff (-r): +The \fB--reverse\fR (-R) and \fB--full-duplex\fR options can be confusing when compared to the +older options of \fB--dualtest (-d)\fR and \fB--tradeoff (-r)\fR. The newer options of \fB--reverse\fR and \fB--full-duplex\fR only +open one socket and read and write to the \fBsame socket descriptor\fR, i.e. use the socket in full duplex mode. The older -d and -r open +second sockets in the opposite direction and do not use a socket in full duplex mode. Note that full duplex applies to the socket +and not to the network devices and that full duplex sockets are supported by the +operating systems regardless if an underlying network supports full duplex transmission and reception. +It's \fBsuggested to use --reverse\fR if you +want to \fBtest through a NAT firewall\fR (or -R on non-windows systems). This applies +role reversal of the test after opening the full duplex socket. (Note: Firewall piercing may be required to use -d and -r +if a NAT gateway is in the path.) +.P +Also, the --reverse -b <rate> setting behaves differently for TCP and UDP. For +TCP it will rate limit the read side, i.e. the iperf client +(role reversed to act as a server) reading from the full duplex socket. +This will in turn flow control the reverse traffic per standard TCP +congestion control. The --reverse -b <rate> will be applied on +transmit (i.e. the server role reversed to act as a client) for UDP +since there is no flow control with UDP. There is no option to +directly rate limit the writes with TCP testing when using --reverse. +.P +.B Bounceback +The bounceback test allows one to measure network responsiveness (which, in this test, is an inverse of latency.) +The units are responses per second or rps. Latency is merely delay in units of time. Latency metrics require one +to know the delay of what's being measured. For bounceback it's a client write to a server read followed by a server +write and then the client read. The original write is bounce backed. Iperf 2 sets up the socket with TCP_NODELAY +and possibly TCP_QUICKACK (unless disabled). The client sends a small write (which defaults to 100 bytes unless -l is set) +and issues a read waiting for the "bounceback" from the server. The server waits for a read and then +optionally delays before sending the payload back. This repeats until the traffic ends. Results +are shown in units of rps and time delays. +.P +The TCP_QUICKACK socket option will be enabled during bounceback tests when the bounceback-hold +is set to a non-zero value. The socket option is applied after every read() on the server +and before the hold delay call. It's also applied on the client. Use --bounceback-no-quickack +to have TCP run in default mode per the socket (which is most likely TCP_QUICKACK being off.) +.P +.B TCP Connect times: +The TCP connect time (or three way handshake) can be seen on the iperf +client when the -e (--enhanced) option is set. Look for the +ct=<value> in the connected message, e.g.in '[ 3] local 192.168.1.4 +port 48736 connected with 192.168.1.1 port 5001 \fB(ct=1.84 ms)\fR' +shows the 3WHS took 1.84 milliseconds. +.P +.B Port-range +Port ranges are supported using the hyphen notation, e.g. 6001-6009. This will cause multiple threads, one per port, on either the listener/server or the client. The user needs to take care that the ports in the port range are available and not already in use per the operating system. The -P is supported on the client and will apply to each destination port within the port range. +Finally, this can be used for a workaround for Windows UDP and -P > 1 as Windows doesn't dispatch UDP per a server's connect and the quintuple. +.P +.B Packet per second (pps) calculation +The packets per second calculation is done as a derivative, i.e. number of packets divided by +time. The time is taken from the previous last packet to the current last packet. It is not +the sample interval time. The last packet can land at different times within an interval. +This means that pps does not have to match rx bytes divided by the sample interval. +Also, with --trip-times set, the packet time on receive is set by the sender's write +time so pps indicates the end to end pps with --trip-times. The RX pps calculation is receive +side only when -e is set and --trip-times is not set. +.P +\fBLittle's Law\fR in queuing theory is a theorem that determines the average number of items (L) in a stationary queuing system based on the average waiting time (W) of an item within a system and the average number of items arriving at the system per unit of time (lambda). Mathematically, it's L = lambda * W. As used here, the units are bytes. The arrival rate is taken from the writes. +.P +.B Network power: +The network power (NetPwr) metric is \fBexperimental\fR. It's a +convenience function defined as throughput/delay. +For TCP transmits, the delay is the sampled RTT times. +For TCP receives, the delay is the write to read latency. +For UDP the delay is the end/end latency. +Don't confuse this with the physics definition of power (delta +energy/delta time) but more of a measure of a desirable property +divided by an undesirable property. Also note, one must use -i +interval with TCP to get this as that's what sets the RTT sampling +rate. The metric is scaled to assist with human readability. +.P +.B Multicast: +Iperf 2 supports multicast with a couple of caveats. First, multicast streams cannot take advantage of the -P option. The server will serialize multicast streams. Also, it's highly encouraged to use a -t on a server that will be used for multicast clients. That is because the single end of traffic packet sent from client to server may get lost and there are no redundant end of traffic packets. Setting -t on the server will kill the server thread in the event this packet is indeed lost. +.P +.B TCP_QUICKACK: +The TCP_QUICKACK socket option will be applied after every read() on the server such that TCP acks are sent immediately, rather than possibly delayed. +.P +.B Fast Sampling: +Use +.B ./configure --enable-fastsampling +and then compile from source to enable four digit (e.g. 1.0000) precision in reports' timestamps. Useful for sub-millisecond sampling. +.SH DIAGNOSTICS +Use +.B ./configure --enable-thread-debug +and then compile from source to enable both asserts and advanced debugging of the tool itself. +.SH BUGS +See https://sourceforge.net/p/iperf2/tickets/ +.SH AUTHORS +Iperf2, based from iperf (originally written by Mark Gates and Alex +Warshavsky), has a goal of maintenance with some feature enhancement. +Other contributions from Ajay Tirumala, Jim Ferguson, Jon Dugan <jdugan at x1024 dot net>, +Feng Qin, +Kevin Gibbs, +John Estabrook <jestabro at ncsa.uiuc.edu>, +Andrew Gallatin <gallatin at gmail.com>, +Stephen Hemminger <shemminger at linux-foundation.org>, +Tim Auckland <tim.auckland at gmail.com>, +Robert J.

For standard iperf the "flow routing" is done using connect() per the ip quintuple. + // The OS will then route established connected flows to the socket descriptor handled by a server thread and won't + // burden the listener thread with these packets. + // + // For L2 verification, we have to create a two sockets that will exist for the life of the flow. A + // new packet socket (AF_PACKET) will receive L2 frames and bypasses + // the OS network stack. The original AF_INET socket will still send up packets + // to the network stack. + // + // When using packet sockets there is inherent packet duplication, the hand off to a server + // thread is not so straight forward as packets will continue being sent up to the listener thread + // (technical problem is that packet sockets do not support connect() which binds the IP quintuple as the + // forwarding key) Since the Listener uses recvfrom(), there is no OS mechanism to detect new flows nor + // to drop packets. The listener can't listen on quintuple based connected flows because the client's source + // port is unknown. Therefore the Listener thread will continue to receive packets from all established + // flows sharing the same dst port which will impact CPU utilization and hence performance. + // + // The technique used to address this is to open an AF_PACKET socket and leave the AF_INET socket open. + // (This also aligns with BSD based systems) The original AF_INET socket will remain in the (connected) + // state so the network stack has it's connected state. A cBPF is then used to cause the kernel to fast drop + // those packets. A cBPF is set up to drop such packets. The test traffic will then only come over the + // packet (raw) socket and not the AF_INET socket. If we were to try to close the original AF_INET socket + // (vs leave it open w/the fast drop cBPF) then the existing traffic will be sent up by the network stack + // to he Listener thread, flooding it with packets, again something we want to avoid. + // + // On the packet (raw) socket itself, we do two more things to better handle performance + // + // 1) Use a full quintuple cBPF allowing the kernel to filter packets (allow) per the quintuple + // 2) Use the packet fanout option to assign a CBPF to a socket and hence to a single server thread minimizing + // duplication (reduce all cBPF's filtering load) + // + struct sockaddr *p = reinterpret_cast<sockaddr *>(&server->peer); + struct sockaddr *l = reinterpret_cast<sockaddr *>(&server->local); + int rc = 0; + + // + // Establish a packet (raw) socket to be used by the server thread giving it full L2 packets + // + struct sockaddr s; + socklen_t len = sizeof(s); + getpeername(sockfd, &s, &len); + if (isIPV6(server)) { + server->mSock = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_IPV6)); + WARN_errno(server->mSock == INVALID_SOCKET, "ip6 packet socket (AF_PACKET)"); + server->l4offset = IPV6HDRLEN + sizeof(struct ether_header); + } else { + server->mSock = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_IP)); + WARN_errno(server->mSock == INVALID_SOCKET, "ip packet socket (AF_PACKET)"); + unsetIPV6(server); + server->l4offset = sizeof(struct iphdr) + sizeof(struct ether_header); + } + // Didn't get a valid socket, return now + if (server->mSock < 0) { + return false; + } + // More per thread settings based on using a packet socket + server->l4payloadoffset = server->l4offset + sizeof(struct udphdr); + server->recvflags = MSG_TRUNC; + // The original AF_INET socket only exists to keep the connected state + // in the OS for this flow.
