Ruby 1.9.3-p0 with ruby-debug19 and performance patches

What is?

This includes the ruby-debug patch Jonathan probably sent you (if you work at Shopify...), and a bunch of performance fixes by Sokolov Yura, aka. funny-falcon. Somebody buy that man a beer.

• http://github.com/ruby/ruby/pull/66
• http://github.com/ruby/ruby/pull/68
• http://github.com/ruby/ruby/pull/83
• http://github.com/ruby/ruby/pull/84

What I need?

• rbenv
• ruby-build

OR

• rvm

How do I do?

If you're using rbenv:

curl https://raw.github.com/gist/1688857/rbenv.sh | sh

If you're using rvm, switch to rbenv. Alternatively:

curl https://raw.github.com/gist/1688857/rvm.sh | sh

Also, putting the following in your shell config (eg. ~/.bash_profile) will make Rails even faster, but will increase its memory footprint a bit:

export RUBY_HEAP_MIN_SLOTS=1000000
export RUBY_HEAP_SLOTS_INCREMENT=1000000
export RUBY_HEAP_SLOTS_GROWTH_FACTOR=1
export RUBY_GC_MALLOC_LIMIT=1000000000
export RUBY_HEAP_FREE_MIN=500000
