From: Eric Wong <firstname.lastname@example.org> To: email@example.com 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.
