+WL#4818 - Stress testing of PERFORMANCE_SCHEMA
+
+The performance schema storage engine is backed by data structures, we
+want to be sure that these data structures are not fragile under
+load.
+
+NFS1: 20 threads doing read of performance data (both mutex and
+disk), 5 threads changing what is being instrumented, 25 threads doing
+DML and DDL so that the statistics are updated. Connections should frequently
+disconnect or be KILLed, and reconnect.
+
+The database should not crash under any circumstance.
+
+How to run:
+
+MTR_VERSION=1 ./mtr --stress \
+                    --stress-suite=perfschema_stress \
+                    --stress-threads=50 \
+                    --stress-test-duration=3600
