At last I could update to 30.0.5.0 and, apparently the issue of high cpu use has been fixed. I'm testing it.

The first post in the thread you linked said it wasn't, and it's not in the release notes, so I just assumed that it wasn't.

Still, I'll wait until you're really sure before trying it. :)

I've been watching videos in you Youtube for nearly an hour now. All is well. CPU max 33.7% and it goes down 2.5%.

There's definitely a question of YouTube not playing nice, but Slimjet 29.0.3.0 handles it better than any version 30.

Version 30 also lags when closing multiple tabs, and that may be a memory problem too.

Continue testing because yesterday it went over 50%.

Let´s hope that team Slimjet fix this, just now went again to more than 50% watching a video in Youtube.

I also have high CPU usage with youtube. In my case even opening youtube without playing video the cpu usage is high.
In slimjet's taskmanager, I notice there is a service worker from youtube that keep on running with high cpu usage. The service worker is running from script "sw.js". Terminate this service worker fix the problem.
So if this is the case that causing your high cpu usage on youtube, you could Install "Reject Service Worker" extension to prevent this problem.

I can confirm that only going to youtube, without watching anything, sometimes, cpu usage goes over 50%.
Also about sw.js, which seems to be the culprit, if you terminate it takes you out of youtube.
Reported this on apr 11 and I have in 2 times sent online feedback with pictures, but nothing happens. I don't know how difficult this is, so I guess we'll have to wait. I'm using youtube in another browser (FF).

You could stop the youtube service worker on sw.js with address:
"slimjet: //serviceworker-internals/?devtools" (remove the space, I cannot post URL, because I am new user) to list all service worker,
then search for "sw.js", stop the service worker and unregister, this won't take you out of youtube.
Also "Reject Service Worker" extension really helpful.

Sorry, I'm a nerd in these things, will wait for Slimjet team to do something.
