The great Ruby Showdown How do the different Rubies out
there perform with a non trivial ruby application? Chris Parsons - @chrismdp Wednesday, 22 February 12
Battleship http://github.com/ threedaymonk/ battleship Wednesday, 22 February 12
Only one round No display GuntherPlayer with fixed random seed
Running on 2009 MBP http://github.com/ chrismdp/battleship My changes Wednesday, 22 February 12
Fixed random seed doesn’t work! Different Rubies do random differently
Need to perform 50 ‘ticks’ instead Also different startup times was a headache Lessons Wednesday, 22 February 12
The players mri 1.8.7 mri 1.9.2 mri 1.9.3 jruby maglev
rubinius macruby Wednesday, 22 February 12
Ruby 1.8.7 • No show - code doesn’t work •
You shouldn’t be using it anyway • Ruby 1.9.2 has out and stable since summer 2010 Wednesday, 22 February 12
MacRuby 0.10 • Ruby based on the Objective-C Runtime •
Long startup time • 442.65s (!!) • 431.90s (!!) Wednesday, 22 February 12
Rubinius (head) • Used: RBXOPT=-X19 rbx -v (can default to
1.9 too) • Long startup time • 56.41s • 52.35s • 90.16s (!) • 94.67s (!!) • 63.07s - very variable! Wednesday, 22 February 12
Maglev (head) • Based on vm-ware’s GemStone virtual machine •
Can “transparently manage very large datasets” • 44.91s • 44.99s • 53.02s • 45.53s Wednesday, 22 February 12
Ruby 1.9.2 • The ‘standard’ during the tournament • Was
focused on a ‘complete’ version of ruby 1.9 • 28.50s • 28.74s • 28.51s • 28.97s Wednesday, 22 February 12
Jruby (1.9) • A number of changes needed to the
app Not an ‘out the box’ change, but still worked after tweaks. • Used: JRUBY_OPTS='--1.9 --server -J-Xmx1024m' • Long startup time: ~ 20-30 seconds • 25.93s • 25.05s • 27.60s • 26.26s Wednesday, 22 February 12
Ruby 1.9.3 • Better GC - doesn’t stop the world
for as long • Focused on a better implementation rather than compliance • 23.64s • 23.80s • 26.30s • 24.67s Wednesday, 22 February 12
The Obligatory Graph mri 1.9.3 JRuby 1.9 mri 1.9.2 Maglev
Rubinius mri 1.8.7 0 20 40 60 80 (lower is better) Wednesday, 22 February 12
