Re: Confused by 'timing' results

PostgreSQL 8.4
CentoOS 5.5
I have got WCE=0, on the drive that mounts the data directory with all its
subdirectory (including pg_log)

Maybe I should try to mount pg_log to a different drive and have write cache
enabled on that one.

It's worth trying alternatives anyway. It is odd that you are seeing
such a slowdown when using the collector --- many people push very high
log volumes through the collector without problems. What PG version is
this exactly, and on what platform?
