I know my dual-core AMD Athlon 64 X2 5200 is not powerful at all, but the problem is that I see how it is at (usually) 20% of usage in idle, and that's not a problem to me, maybe it just can't do much more... However, I note how sometimes it's "powerful", but sometimes no. I don't know if that's package-related, kernel-related, or some services... But the point is that it takes to 80/100% quickly for the most simple tasks I could do. Yes, it happens with Firefox obviously, but taking 50/60% when browsing throug my files isn't normal.

I have noted this behavior is not normal because I have seen how it can do much more in the past or in some rare occasions, so something makes me feel that there is an issue that cause my apps to use more cpu cycles than it should, all apps, nor only ... Or as if my graphics card were not used.

I have never tested Windows or other systems than MX Linux 19.2, so I can't test it in deep, however, I had the MX default Linux Kernel 4.19, and I note a very little difference (to better) when using current.

A process is ever consuming more CPU resources than usual is Xorg. I don't know if that's normal because it's persistent, always between 5% and 15%. But as I have a graphics card, I don't know why xorg needs that space or if it's affected/it affecs other processes.

I need to at that this sacrifice my CPU a lot because it's always overheating, so in the night this effect is a bit mitigated.

Is this maybe happening because of some kernel patches or wrong libreries configuration? Please request whatever additional information you need.

  • Examples: Scrolling in Firefox sums around 30/40% usage, while a gif on the page could cause a 60/70% usage. With Firefox this problem is so hard.

  • Scrolling up and down in the whisker menu is also significative (+30/35%)

Maybe something is wrong with cooling of this CPU and it is speedsteping to some lower MHz than usual?

  • It's a good highlight and something I have not thought... Could you add ways to measure the CPU MHz in real-time and in that way possibly get conclusions? — In my attached details, it's shown that my CPU has Speed: 2700 MHz min/max: 1000/2700 MHz Core speeds (MHz): 1: 2700 2: 2700 — Not evident thermal throttling here.

  • I'll let it stand for now, but yeah - this is closer to a comment than an answer. Commented Nov 2, 2020 at 19:29
