Just a guess: you might actually be running the CPU at a low frequency. As in the frequency scaling driver isn't working.
Maybe poke around on a performance monitor tool. Seems like there's "Plasma System Monitor" on KDE. Make sure the tool can see all the RAM, all of the CPU cores (2x physical cores with Intel hyper threading).
It should also report the CPU frequency, which should go up and down depending on the load. You can also check that the CPU temperature report is reasonable.
This also gives you process info, so when one of these 5 second freezes happens, you should be able to see what shoots to the top of the list. Or maybe there's a background task churning through a bunch of stuff. Or maybe the flash access is really slow.
This is it. CPU is throttling itself due to high temps. Not i just need to figure out why it's so hot
Is your cooling system on?
Hot CPU?
Is the CPU fan running?
Is CPU usage stuck high?
A lot of dust in the cooler fins?
Is it a stock CPU or aftermarket?
Is the plastic sticker off of the CPU cooler?
Enough thermal paste on the CPU?
Screws tightened down enough on CPU cooler?
That's pretty much the order of diagnosing CPU air cooler problems lol
Or tightened too much? And/or unevenly?
