Check per-process I/O usage: - - Use `iotop` to see the processes that are the main I/O consumers: - - ``` - sudo iotop - ``` - - If you don't have `iotop` installed, then [install it](https://www.tecmint.com/iotop-monitor-linux-disk-io-activity-per-process/) - -2. Analyze the running processes: - - Investigate the top I/O consumers and determine if these processes are expected to consume that much I/O, or if there might be an issue with these processes. - -3. Minimize the load by closing any unnecessary main consumer processes: - - If you find that any unnecessary or unexpected processes are heavily utilizing your disk, try stopping or closing those processes to reduce the load on the disk. Always double-check if the process you want to close is necessary. - -4. Verify your disk health: - - Make sure your disk is not facing any hardware issues or failures. For this, you can use the `smartmontools` package, which contains the `smartctl` utility. If it's not installed, you can [install it](https://www.smartmontools.org/wiki/Download). - - To check the disk health, run: - - ``` - sudo smartctl -a /dev/sdX - ``` - - Replace `/dev/sdX` with the correct disk device identifier (for example, `/dev/sda`). - -5. Consider upgrading your disk: - - If your disk consistently experiences high latency and you have already addressed any performance issues with the running processes, consider upgrading your disk to a faster drive (e.g., replace an HDD with an SSD). - -### Useful resources - -1.
