err, I just remembered that I did not reply fully to your question
Re: difference of 400Mb between 22 and X: it may be a difference in the compilation of the 2 kernels, or the Halium part (the X is Halium 10, the 22 is Halium 11) could be bigger... As Volla is delivering the OS they may be of help in replying to this question (unless you flashed it yourself with the UBPorts installer, in this case you are at the right place to ask)
Re: 'laggyness'
since your real problem is that you feel that your device is slow.
About the swap: I have quite some experience with Linux and I have never felt a real slowness when swap is at a reduced level like in your case 10% of use or less.
It's difficult to guess of course since I don't have a real-time display of the swap splashed on my screen.
When I have ever felt slowness, I usually check the swap and when it's at over 50% I'm sure that's the culprit.
You see, swap don't decrease naturally by itself. When a program needs a lot of memory, some swap may be allocated, then the program frees the memory, but the system will not naturally decrease the swap. Things are very complicated under the hood. So you can have a bit of swap allocated and everything is all right really. But when swap goes over 50%, it's really frequent that you have a badly programmed software running amok, and unless it is stopped it will go on and eat all swap and then it's time for the big red button.
So the little swap you show us here may be a symptom of something significant, or it may not.
My advice: if you use heavily your phone for Internet browsing and you use Morph as packaged in the OS, stop it. It has an old code base that could badly interact with the current state of the Web. Recommended alternatives: anything else really; the QT6 preview of Morph, Firefox, Librewolf, Min by PParent (I tried it briefly this morning and did not see anything wrong with it, don't know if the name should carry an expectation it's really less resource hungry than the previously cited alternatives browsers).
Give a try to these alternatives and if one really consumes less memory and feel faster, don't hesitate to report ! You are not the only one with limited memory, even I have only 8 (err 7.1) Giga !
I can't stress enough how modern browsers are gigantic and complicated pieces of software and as eating too much memory is a common problem, and can be a cause for excess swapping. If your slowness is perceived only in browsing, even without eating too much memory an old browser can be slow because it don't understand new features of the current web.
