It is a good thing it exists natively in Chromium, since Developers can use some features to work with it and make the experience of ‘discarding’ tabs better īut 2 minutes is too short and 1 hour too long. That will puts the tabs to sleep, the problem is as you can see by the ‘high efficiency’ one is that times are bad, by default it is 1 hour, and then 5 seconds to 2 minutes only, not even 30 minutes or 15 minutes or something better. That’s why using ‘average’ CPU % for total of CPU usage is really bad, it’s not like it is showing you the real usage per core, so Windows does it right by using 8 cores = 100% and Chromium and whatever OS are doing it dumb.Īnd well, Brave (because of Chromium) added two flags, chrome://flags/#battery-saver-mode-availableĬhrome://flags/#high-efficiency-mode-availableĪnd you enable it here and can have exceptions for sites brave://settings/performance Well, you are using only 19% of your 100% CPU if you have the 8-core, so that’s pretty much nothing. The problem is Facebook is crap, you can run extensions like FB Purity and it will still be terrible slow website, just a tiny little bit better. You can also use the flag brave://flags/#site-isolation-trial-opt-out (which I think uses -disable-site-isolation-trials to disable the site isolation) You can remove them if you run brave with -no-sandbox and/or -disable-features=IsolateOrigins,site-per-process but not recommended. There is also sandboxing which uses more resources to secure the browser. It can be disabled but some sites seem to need it to work properly, well I have notice the ones that check if ‘your connection is secured’ especially, like cloudflare have problems if you don’t enable it. but 158% still would be “1 core and a half” being used, so unless you had 2 core CPU, or maybe 4 cores, I don’t see the problem.įacebook has too many garbage scripts, so even with Adblocker it is slow and crap, especially messages since they made it a whole messaging to be used with FB messenger app.Ībout the subframes, it is normal, and it is one of the security measures Google added to Chromium to fight against vulnerabilities, It is called Site Isolation, so by the name you can see what it does. 158% is not 100% CPU in Chromium task manager, how many CPU cores do you have? because each 1 CPU core = 100% so depending on your CPU core count, it can be nothing or almost nothing.
