How to properly optimize Linux Mint (XFCE)?

Question

ubuntu

Above are the specifications of my computer. I perfectly understand that it is weak and the problem is this: despite the fact that I have the XFCE graphical shell, there are noticeable delays when moving windows or when opening multi-threaded software.
I installed a proprietary driver through the driver manager (recommended by nvidia-340), added the standard nouveau to the blacklist, but nevertheless nothing changed (in the end result). that is, yes, when the standard driver was installed, there were serious brakes, but after installing the proprietary one, everything improved significantly. I also changed xfwm4+compositing to xfwm4 in the window manager and removed the visual effects, but the brakes are still felt.
Again, the system was chosen based on statistics. did not poke at plasmas, mates, synamons, and so on. before that, I also tried lubuntu, but the appearance was not at all impressive. no race for a fresh design, but xp looks nicer than the lubuntu shell.
I checked the top processes and the peak CPU load was 20%, no more. How to be in such a situation?

Answer 1

Actually, the main question here is what is planned to be done on this computer later?
If the answer is to surf, or watch streaming video, for example, then you can simply not bother and throw out this iron. This will be virtually impossible to do, regardless of the installed OS, and the choice of distribution - the bottleneck will be a very voracious browser, or a lack of processor performance to decode video in normal quality.
If the answer will use the console, then you don't need any optimization, you just need to throw out the DE as such. It will be possible to write something in vim or emacs, go to servers via ssh, etc. Without any brakes... =)
Even compiling or debugging something not very large on such a computer will be quite normal.

Answer 2

The computer is old. Don't really improve anything. On Windows it will probably work even better.
