>That's hardly surprising since it isn't a problem with the operating system. Your machine is incapable of meeting your excessive expectations of it. Even the lowly Intel Atom line of CPUs out-perform the Pentium N3540. Once you go beyond basic email and simple web-browsing, that machine simply is not going to cope.
>Hi everyone, sadly all recommendations did not change anything. However I've been testing a Fedora 33 live image with Xfce and things works perfectly, I've been in more than three meetings with Google Meet (even sharing my screen) and one with Zoom and had no problem at all. I know my hardware isn't very good, but I was sure the problems were not all due to my machine. All my experiences and "experiments" with this issue suggest to me that this is a Debian related issue as I had the same trouble with Debian-based distros. I think I will change to Fedora permanently as this solved my problem. Thank you all for your help and your time.
