My computer goes significantly slower without JIT.
Is this for Petstore 1? Are you sure it's not just swallowing
exceptions?
My setup:
Hardware: IBM Thinkpad R40, an older one (Intel(R) Pentium(R) M
processor 1300MHz, 1024MB cache, 1199.90 bogomips)
OS: Ubuntu 7.04
Kernel: 2.6.20-16-generic #2 SMP Sun Sep 23 19:50:39 UTC 2007 i686
GNU/Linux
Ruby: ruby 1.8.5 (2006-08-25) [i486-linux]
Database: MySQL 5.0.38
Application: Petstore rev 177,
http://tw-commons.rubyforge.org/svn/petstore/trunk
Java: build 1.6.0-b105
Rails: 1.2.3
ar-record: 0.5
echo 'load "script/benchmark_action"' | ~/jruby_/trunk/jruby/bin/jruby
-J-server -J-Djruby.jit.enabled=true
-J-Djruby.objectspace.enabled=false script/console ar_jdbc
I also checked ar_jdbc.log, but found nothing (but tons of SQL queries
and stuff like that)
Maybe I'm doing something wrong, but I can't imagine what it is.
Previous tests on a
Windows box showed the same results.
I find it also interesting that the numbers you posted yesterday or so
show the same
MRI/JRuby ratio like mine do when the JIT is turned *ON*. When I
disable the JIT,
the ratio is better than with your results.
What's the version of your JVM?
Christian
I'm running 1.6 on Mac.
Could you try modifying script/benchmark_action.rb, the method
perform_acttion so it prints exceptions, and see what happens?
