Oh, and regarding JRuby versus Python 3...yes, if Ruby 1.9 smokes Python, and JRuby is faster than Ruby 1.9, then JRuby should smoke Python even more. I have not done the comparisons myself, though.

a) There will be problems in the Computer Language Benchmark. Like with the excellent LuaJit, they only allow one version of a language, so a war of implementations to appear would not be surprising. b) Now that Python is in a difficult transition to Python 3, a strong ruby is a game changing point.

It is also important to mention that java7 G1 garbage collector gives much better results for certain installations (of course test it before deploying it on production). The pauses are much more predictable and, in my case, much shorter. Here is how to get Oracle Java7 on Ubuntu: wget http://download.oracle.com/otn-pub/java/jdk/7/jdk-7-linux-x64.tar.gz tar -xvf jdk-7-linux-x64.tar.gz sudo mkdir -p /usr/lib/jvm/ sudo…
To enable G1 on Java 7: -XX:+UseG1GC. Prepend -J if passing to the 'jruby' command.
I've been eyeing jruby for quite a while but never had much success with it. There seems to always be the odd gem not supporting it (e.g. jruby-openssl is broken which a lot of my stuff depends on).
OpenSSL is a terribly complex library to support, but we've managed to steadily improve our pure-Java port (originally a herculean effort by Ola Bini, it wraps bouncycastle in an OpenSSL-lookalike API). There's still probably issues, but we have tried to fix them as they come up.
Fwiw, I'm currently blocked on http://jira.codehaus.org/browse/JRUBY-6260
Apparently the fix is already done but hasn't made it into the 0.7.5dev gem yet.

jruby-openssl has worked fine for me for several years. Making outgoing SSL connections was one of the primary functions of the last app I worked on.
So I'm looking forward to the 0.7.5-release and with a bit of luck I might finally be able to jump on the jruby-bandwagon then.

I know some of the implementations there use native libraries that are built into python but only available via RubyGems for Ruby, like numpy. That makes it less of a language shootout (at times) and more of a "who ships the best C libs" shootout. I believe MRI is generally faster than Python now when they're doing roughly equivalent work in Ruby and Python.
Specifically?

Show me the numbers ;-)
10-30% faster is “massive”? Ruby standard is 5-30 times slower than all other popular language implementations, I'd expect at least a 100% increase to be considered “massive.” I'd call this just “a speed boost.” Anyway, keep it up.
Three times faster == 300% speed increase. In your terms that would mean a _really_ massive upgrade.

No, it's a 200% speed increase . If the speed before was 1 unit, it's now 3 units. That's 200% more.
