Did you recently upgrade? Anyhow… here are a couple recent threads with high cpu usage rebuilding may help > [@High CPU usage (Ruby)](https://meta.discourse.org/t/high-cpu-usage-ruby/348913/22): > > Yeah fair play to the DC team they are usually very good. If I hadn’t have moved two other forums over I could have been more confident in saying it was related to up update (even though my hunch was saying it probably was) glad you and @markschmucker were on the ball and noticed the increase as well! Welcome to Discourse btw! +1 > [@Increased CPU Usage since 3.4.0.beta4-dev ( 58f75ed205 ) upgrade](https://meta.discourse.org/t/increased-cpu-usage-since-3-4-0-beta4-dev-58f75ed205-upgrade/350200/11): > > Note, closing the loop, the bug causing it was this: [https://github.com/rubyjs/mini\_racer/commit/edaa9e862abcd9945fbfcdd115d02dd7326569cf](https://github.com/rubyjs/mini_racer/commit/edaa9e862abcd9945fbfcdd115d02dd7326569cf) I updated the gem. One immediate advantage is that it appears this version of v8 uses slightly less memory which is nice. > [@Post 3.5.1 update - CPU maxed out 100%](https://meta.discourse.org/t/post-3-5-1-update-cpu-maxed-out-100/350530/5): > > Rebuild has worked and calmed things down so far. I do not see those postgres process in HTOp or at leat they are not anywhere near the top like before. --- _[View the full topic](https://meta.discourse.org/t/server-performance-issues-due-to-high-cpu-usage/333279)._
