First-off, 6.0-RELEASE may be new to the block, but 6.0 has been > kicking it almost as long as 5.4-RELEASE has been out.

Certain key optimizations in 6.0 will > help you out, (eg filesystem changes, SMP support, hardware drivers, etc). I just phased in a new postgresql db-server based on the 6.0 release. I did stress-test it doing an import, making buildworld and buildkernel, reinstalling ports etc. trying to put as much load on the cpu and disk-io as I could and it behaved fine. Three things changed, I went from four single core opterons to two dual cores, from four to eight GB ram and from FreeBSD 5.4 release to 6.0 release. My timing is not optimal since we're somewhat busy but we need the additional four GB ram. Postgresql only got the minor upgrade from 7.4.8 to 7.4.9. The improved smp- and disk-io (from what I read) under 6.0 and the stability during my testing made me go for this release. I'll let you know on monday how it went. regards Claushome | help
