I'm having some slowndowns in my postgresql server, and I had been reading
something about checkpoints, that could resolve my problem.
Now, I have:
checkpoint_segments = 30 # in logfile segments, min 1, 16MB
#checkpoint_timeout = 5min
And I percebed that this slowndown is occuring for 5 min...! So I'm suposing
that the problem is in the checkpoint_timeout.
What's the impact to chang it to:
checkpoint_timeout = 2min or
checkpoint_timeout = 5min
