Haven’t upgraded the forums for a while but did so yesterday and the server loads have increased. I have a feeling it may be connected to what was discussed in these threads: High CPU usage (Ruby) and Increased CPU Usage since 3.4.0.beta4-dev ( 58f75ed205 ) upgrade Mentioning @markschmucker and @LotusJeff in case they’ve noticed the same.

Have you been updating fairly regularly? I hadn’t updated for quite a while hence the jump seems noticeable to me. I wish I had made a note of the previous version now… wonder if there is a log file that records version numbers and time spent on them?

Do you use chat? Maybe it’s the indexing for chat search [image]Introducing chat search After updating to the latest version of Discourse, a background job will run to index your chat messages and make them available to search. Until this process is complete (which can take multiple days for communities with lots of chat messages), some messages may not show up in chat yet.

It does seem a little better today so it could have been that Moin. I’ll observe for a few days and see how it goes.

I’m slightly behind at 3.6.0.beta2-latest but do not see increased CPU.
