rwjblue

#Overview drip is an awesome command line tool that can be used to dramatically lower perceived JVM startup time. It does this by preloading an entirely new JVM process\instance and allowing you to simply use the preloaded environment. This has extraordinary results with jruby.

We reduced time to run rake environment from 13 seconds to a mere 3.5 seconds. This is actually at or near MRI 1.9.3p327 (with falcon patch) speeds!

Adding a few addition jruby options will reduce startup time even further (down to 1.69 seconds).

#Install Drip Install drip if you haven't already (see https://github.com/flatland/drip)

require "fiber"

module Middleware
  # This is a basic runner for middleware stacks based on Ruby fibers.
  # By using fibers rather than recursion, the stack is not deepened, and
  # therefore cannot stack overflow. This allows middleware sequences of
  # thousands to be used without crashing Ruby.
  #
  # This runner is much more complicated than the normal runner because it
  # has to do a lot of work to _simulate_ a call stack. For example, one of

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
