Benchmarking JRuby

Charles Oliver Nutter

12/2/2007 12:10:00 AM

For those of you playing with JRuby, if you run across benchmarks of any
kind that show JRuby running slower than Ruby 1.8.x, we'd appreciate you
filing them as bugs:

http://jira.codehaus.org/br...

In general, performance in JRuby should be better for normal execution,
so we'd like to find any remaining performance bottlenecks. Poor
performance is a bug!

Thanks for your help!

You've got PetStore running faster than 1.8 now??

I don't think it's quite there...and it ought to be, so there's
something slowing it down. Other Rails benchmarks, however, do show
JRuby running faster. Work continues.

nice timing...

Antonio Cangiano just completed a new run of his Ruby language shootout.

Major improvement on Feb's numbers, impressive stuff.

Yeah, and Antonio's numbers don't even reflect true performance after
the VM warms up and things JIT. There's really only about two YARV
benchmarks we're slower on now.
