On 2.5 I see approx 50% slowdown when GC is in progress. Same slowdown
is present when 'delete from test' is executed.
Nothing special for GC, but must say that master seems to miss even this
slowdown. Rather hard to say for sure cause execution time of test
connection varies from 0.01 sec to 0.02 sec for 2.5, not more. For
master it seems to be almost always 0.01.

But nothing looking like irresponsive server. FYI:
