[Cross-posting after lack of response on -stable]
are there any obvious changes between 6.0-BETA3 and 6.0-RELEASE / 6.0-
STABLE that I should be aware of, that could cause a quite noticeable
decline in performance (and a change in performance patterns) for
On a BETA-3 system I'm seeing, with the particular application we're
running, about 28 transactions/second over a 10 minute interval. With
-RELEASE and -STABLE I'm lucky to reach 24, and it'll usually wobble
Another oddity is that where the BETA-3 system starts out with good
performance from the beginning when running load tests, the -RELEASE
and -STABLE systems need a good 20 seconds to reach their "max",
starting out very low (3-10 transactions/second for the first 10
seconds or so).
This is on HP DL385 servers with dual 2.4ghz Opteron CPUs, running
FreeBSD-amd64 from 15kRPM drives in cached RAID.
Hardware and software configuration (apart from the base system),
network configuration and latencies, database access, etc. is 100%
equal on all systems.
