We want to reduce GitLab's memory consumption. In order to do that we first need to profile our primary processes and determine where our best opportunities are for improvement. @stanhu is going to perform this analysis and suggested that we approach this on three fronts: - Unicorn (gitlab-ce#49702) - Sidekiq (this issue) - Gitaly (gitaly#1298) I'm creating these issues so we can track our findings and create related issues for specific fixes.
