Hello there,

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 each
#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

Tnhks,

Rafael Domiciano
