Has anybody experimented with JRuby?
I've been using it for local development for awhile. It works fine
and usually feels just as fast as MRI once it gets running. The
startup time is really slow, but I've heard that the latest release
fixes that a bit. http://archive.jruby.codehaus.org/dev/481A4453.3060307%40sun.com
It has these pockets of inconsistent sluggishness though. Like at one
point I think I was just doing String#constantize in a rails app and
my processor spiked for like 3-5 seconds before producing a result. I
theorize that it has something to do with how heavily Rails
monkeypatches the core classes.
Hopefully http://code.google.com/soc/2008/ruby/appinfo.html?csaid=3A00346D0DF1DDE6
will resolve some of these inconsistencies. I'm really excited to
have a high-performance ruby implementation that my ops team doesn't
have to even be aware of :)
