I took the various VM’s for a test drive the other day, running some rails benchmarks.
Tested were rubinius 1.0.1 (with JIT),
jruby 1.6.0.dev (ruby 1.8.7 patchlevel 249) (2010-06-03 2b166c9) (Java HotSpot(TM) Server VM 1.6.0_18) [i386-java], ruby 1.8.7p249 (linux, 32-bit), and ruby 1.9.1p376 (linux, 32-bit).
All were tested in a Virtualbox 3.2.2 with 2 cpu cores assigned to it, using the rails benchmarks from the ruby benchmark suite
(rails 2.3.8, single threaded).
Linux version 2.6.32-22-generic (buildd@rothera) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #33-Ubuntu SMP Wed Apr 28 13:27:30 UTC 2010
Here’s how they fared:
Interesting to note is that 1.9.1p376 is a bit faster for most things, 1.8.7 isn’t far behind, and is fastest for running the unit tests.
Jruby and rubinius, despite making great strides in execution time, are still a bit slower.
I had expected jruby to do better based on http://blog.pluron.com/2009/05/ruby-19-performance.html but it seems that, for me at least, it still falls behind (I’ve heard a few other people with similar results).
Also note a windows benchmark of the same.
Any other rails benchmarks you think should have been included?
