Performace patch for ruby-1.9.3-p327

Changes:

  • this version includes backport of Greg Price's patch for speedup startup http://bugs.ruby-lang.org/issues/7158 .

    ruby-core prefers his way to do thing, so that I abandon cached-lp and sorted-lf patches of mine.

  • this version integrates 'array as queue' patch, which improves performance when push/shift pattern is heavily used on Array.

    This patch is accepted into trunk for Ruby 2.0 and last possible bug is found by Yui Naruse. It is used in production* for a couple of months without issues even with this bug.

October 19 2012 - rubygems.org - notes on server

[transcript from http://www.youtube.com/watch?v=z73uiWKdJhw and irc]

Why is the server unhappy?

  • Bundle API is 70%-80% of traffic and it has to resolve the dependency graph and Marshal
  • x Processes are spinning in Ruby with 380% (of 400% total CPU [4 x 100%])
  • x Bundle can only use vanilla gems, so that's why we have to use Marshal
  • Redis Heapsize
  • Diskspace

Timing - middle of the day US

# Monkey patch to Sprockets::StaticCompiler, a class provided by actionpack
# that's used by the assets:precompile task. This patch uses the Parallel gem
# to parallelize asset compilation in the simplest way possible.
#
# Parallel wraps Process.fork to handle things like inter-process communication
# via pipes and determining the maximum number of processes to run based on
# your system's total logical processors. So far only tested on MRI 1.9.3 on OS X.
