I checked out the latest updates about 14 hours ago.

I've also put together a new box, featuring an Athlon running at 1.3 Mhz. I cloned the 
OS (Red Hat Linux 7.1) - I'd copied it from one disk to another fairly recently, and 
so the software setup is pretty well precisely what I've been using all along.

A job which took well over three hours on my Pentium II@133 (mostly CPU time) runs in 
a little over two (mostly I/O), a result that doesn't surprise me a lot.

It crossed my mind that PG is probably using new log files all the time:


2001-09-15 20:26:56 [30787]  DEBUG:  recycled transaction log file 0000000000000032
2001-09-15 20:29:36 [30788]  DEBUG:  recycled transaction log file 0000000000000033
2001-09-15 20:29:36 [30788]  DEBUG:  recycled transaction log file 0000000000000034
2001-09-15 20:35:11 [30791]  DEBUG:  recycled transaction log file 0000000000000035
2001-09-15 20:35:11 [30791]  DEBUG:  recycled transaction log file 0000000000000036

and so on.

I think that if it actually reused them instead of deleting old files and creating new 
ones then on my system (256 Mbytes of RAM) a few log files would fit entirely in cache 
and it would really fly.
