Exactly the same thing observed happening with both AppImage and .deb installations; and on both Linux Mint 22.3 and Pop!_OS 22.04
This actually appears to be exactly the issue described here: https://yaak.app/feedback/posts/high-cpu-usage-while-doing-nothing – supposedly fixed, but something very similar appears to be happening again..?

Can you give me a bit more info as to what features of Yaak you’re using? Does it happen immediately upon starting Yaak?
Hi Gregory, thanks the quick response.
Yes, it just immediately jumps to 110 - 115% when starting up the app and doesn’t budge! It doesn’t seem to correspond to usage of any particular feature.
(As far as what I’m doing with Yaak– I just have a git-managed workspace with about 20 or so requests in folders. It was imported from a json file. I’m using some global vars, set with request-chaining. But I saw this happening with a fresh install)
Thanks for the screenshot! Quick question: is your sync folder its own Git repo, or a folder inside a larger repo (eg. a large code project)?
I ask because Yaak watches the entire repo that contains the sync folder — so if that repo is big and busy, that could explain the constant CPU usage.
Yes, exactly; it’s a folder at the root of a larger repo (with vendor / node_modules / etc), so perhaps that’s it.
Was this not the intended way to use Yaak? I would have thought just including/committing the Yaak schema as part of an associated codebase makes sense.
In any case, I confess I’ve now uninstalled Yaak in favour of Bruno which seems a better fit for me. I’ll keep an eye on the project though. Thanks for looking into this.
Yep, this is intended, I was just trying to narrow the bug. I will improve this so large repos don’t slow it down. Thanks for the info!
