I switched from Zorin Core to Lite but even after this I have performances issue with my laptop. It's faster than Zorin Core and windows 10 but sometimes I work for 10 mins and it crashes I have no idea why, all is froze and after fews mins it doesn't unfreeze so I have to restart using power button which is annoying.
I wonder how I can improve that. It looks like if an app is taking too much ressources it doesn't pause or stop process so even OS itself has problem.
I noticed that brave browser was taking a lot of RAM it might be the reason?
As you can see on your screenshot, you have a ton of crash reporters running, so try opening their corresponding app and disabling problems reporting and crashes handling options to see if performance improves.
I think that too, your ram 4 gig, and a lot of opened tabs in brave or chrome browsers consume your ram.
to avoid that , u need to use extension in your browser to sleep unused tabs. or you can use (nohang) tool , it's good tool that notify u to close unused tabs or unused apps before craching.
By the way, for those who know, is it normal to have so many identical or similar processes apparently doing the same thing with such high memory usage?
