select benchmark(50000000,(1234*5678/37485-1298+8596^2));
Return result in 11.1261 seconds.

select * from performance_schema.setup_instruments where name like 'wait/sync%' and (enabled='yes' or timed='yes');
Return no result.

Composite indexes helped a lot. Difference is really huge.
CPU Ussage now is jumping from 0% to 30% (sometimes 80%) when there are 200 online users on the site at the same time. Iis it fine or should be still lower?
