Description:
Please see documentation as below.
https://dev.mysql.com/doc/refman/5.7/en/performance-schema-startup-configuration.html
===
To disable all instruments, use this option:
--performance-schema-instrument='%=OFF'
===
I set configuration as below.
===
[mysqld]
performance_schema = ON
performance-schema-instrument='%=OFF'
===
However, not disable all instruments.
(memory/performance_schema/% not disable.)
How to repeat:
set configuration as below and mysqld restart.
===
[mysqld]
performance_schema = ON
performance-schema-instrument='%=OFF'
