Bug reference:      1410
Logged by:          Simon Nicholls
Email address:      simon(at)mintsource(dot)org
PostgreSQL version: PostgreSQL 8.0
Operating system:   WindowsXP
Description:        Hibernate PerformanceTest is incredibly slow (in effect
unusable)
Details: 

Using WindowsXP, JDK1.5, Hibernate 3.0 beta1, & PostgreSQL 8.0.0-rc5-3, I
ran the Hibernate PerformanceTest. Whilst it runs fine for MSSql & MySQL
(thus I believe Hibernate is ok), PostgreSQL takes way too long to complete.
I've tried with all 3 versions of the PostgreSQL jdbc driver, & also the
updated jdbc builds on the web site, but that has made no difference.

I've included the JUnit output at the bottom, & here are the MySQL InnoDb
results - simply to give a general ball-park idea of test timings. I'm
running a 2.8 GHz P4 with 1Gb ram, & only the minimum software needed for
test (I believe). CPU usage is very high throughout the test. Thanks for all
the great work so far btw, & I hope this is something obvious.
