With 4 clients and scale 10 I get 246 TPS for synchronous_commit
disabled and 634 TPS for synchronous_commit enabled. So the effect just
got even stronger. That was for CFQ.
For deadline they are now pretty close, but synchronous_commit disabled
is still slower. 690 to 727.
Values are AVG from 3 runs each. DROP/CREATE DATABASE and CHECKPOINT;
before each run.
