Subject: nakayoshi_fork for CoW memory use reductions
Date: Mon, 26 Jun 2017 02:21:36 +0000
Message-ID: <20170626022136.GA27608@whir> (raw)
I thought I posted about when I first heard about it, but
apparently not.
It's a RubyGem which should help with CoW memory savings
for Ruby 2.2+ due to the introduction of generational GC.
https://rubygems.org/gems/nakayoshi_fork
git clone https://github.com/ko1/nakayoshi_fork.git
You can also get a similar effect calling GC.start(full_mark: false)
four times in the unicorn before_fork hook, but nakayoshi_fork
is a bit more sophisticated in that it stops looping when it knows
it can't proceed.
Anyways, I was reminded of this while responding to
https://bugs.ruby-lang.org/issues/11101
which may affect some unicorn users, too.
