slow

Hi!

I'm currently using passenger with ree 1.8.7 in production for a rails 2.3.5 project using postgresql as a database.

ab -n 10000 -c 100: 285.69 [#/sec] (mean)

I read jruby should be the fastest solution, so I installed jruby-1.5.0.rc2 together with jdbc postgres adapter and glassfish. As the performance is really poor, I also started running my application using "jruby --server -J-Druby.jit.threshold=0 script/server -e production". Anyway, I only get

ab -n 10000 -c 100: 43.88 [#/sec] (mean)

Thread_safe! is activated in my rails config. Java seems to use all cores, cpu usage is around 350% (top).

ruby -v: jruby 1.5.0.RC2 (ruby 1.8.7 patchlevel 249) (2010-04-28 7c245f3) (Java HotSpot(TM) 64-Bit Server VM 1.6.0_16) [amd64-java]

I wonder what I'm doing wrong and how to get better performancre with jruby than with ree?

Thanks, Corin
