Patched ruby 1.9.3-p194 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p194 with patches for boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.

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

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.

	# Just wanted to clarify my points at the meetup last night.
	#
	# There were two different issues intertwined:
	# (1) Whether to use extend or "include as extend"
	# (2) When using "include as extend", what is the simplest way to achieve the goal?
	#
	# My personal opinion is that the answer to (1) is "extend", not "include as extend", but that
	# is just my personal opinion. My answer to (2) is a more empirical question.

	# Using the "extend" approach. Again, I personally prefer the simplicity of this approach, but

	# This is the code from my 'There is No Such Thing as Metaprogramming' talk,
	# which premiered at the Arlington, VA Ruby Users Group on Feb 22nd.
	# Without the deliver and walk-through to the solution below this example
	# will be missing quite an important bit of content (mainly the tracking of
	# 'self' while developing the solution, but it still a useful read.

	# Here is the Toddler with no metajuju. Note that the developer, as well as
	# the code, is completely unuaware of the interpreter. A developer with a
	# background in compiled languages would be comfortable looking at this.

	require 'thread'
	require 'json'
	require 'net/http'
	require 'uri'
	require 'betabrite'
	require 'psych'
	require 'usb'

	class StreamClient
	def initialize user, pass

	# autoload concerns
	module YourApp
	class Application < Rails::Application
	config.autoload_paths += %W(
	#{config.root}/app/controllers/concerns
	#{config.root}/app/models/concerns
	)
	end
	end

	# First, I suppose you have ruby 1.9.1 or 1.9.2
	# Open irb. Execute this:
	# RubyVM::InstructionSequence.compile_option = { tailcall_optimization: true, trace_instruction: false }
	# Note, RubyVM::InstructionSequence.compile_option() doesn't have item :trace_instruction, still, you need to specify it. WTF?
	# Also, it doesn't work if you just put it to the script. Don't know why yet. Tell me (@rofh) if you know.

	# Then open the file:
	# require "./tail-recursive"
	# Then execute function:
	# fact(30000)

	find ~ -name '*.log' -print0 \| xargs -0 -L1 stat -f'%z %N' \| sort -rn \| tee fat-logfiles.txt \| head
