The 2010 Ruby Implementation Performance Shootout

By Peter Cooper / July 20, 2010

Hot on the heels of his Windows Ruby implementation shootout comes Antonio Cangiano's Great Ruby Shootout of July 2010 where Antonio pits 8 different Ruby implementations against each other in a performance shootout!

Antonio's findings and observations are interesting and well worth a read (particularly the parts about memory consumption) but if you're in a hurry, the conclusion is that Ruby 1.9.2 RC2 and JRuby 1.5.1 are almost joint first place for fastest Ruby implementation (but 1.9.2 takes it by a hair.) Ruby 1.9.1 and Maglev are then very close behind.


  1. Jonas Elfström says:

    It would be interesting to find out why JRuby needs 199MB to run bm_sudoko.rb while Ruby 1.9.2 only needs 4.3MB. Initial overhead does not seem to explain the huge difference in memory consumption between the two.
