Hi,

There are some issues on my mysql servers.
I just changed the configuration for innodb table space from system table spaces to file per table spaces.
In results, CPU usage get higher than before.
There are 30 patitining tables. The size of each table is about 200GB.
Total size is about over 6TB.
I want to know how to reduce the usage of cpu.

which one is better for performance between system table spaces and file per table spaces ?
