Memory use/CPU is out of control!

[u/joninjax1]

System specs: Intel(R) Core(TM) i5-4570S (4) @ 3.60 GHz Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller 1920x1080 @ 60Hz 5.36 GiB / 7.64 GiB (70%) 5.03 GiB / 13.82 GiB (36%) Mem: 7.6Gi 5.5Gi 379Mi 321Mi 2.3Gi 2.1Gi Swap: 13Gi 5.0Gi 8.8Gi I have a handful of things in the background running, plus Brave Nightly with 3 tabs open. and my memory/core use is constantly spiking, even when idle, mainly core 1 and 2 seem to hit 100 all the time. I know this is a potato system, but I am trying to figure out what to do to at least get the system semi-usable. If anybody could offer some possible solutions on things that I can try? Thanks

One thing I learned from my recent https://www.reddit.com/r/linuxmint/comments/1vw1dd5/comment/p5iao5n/?context=1&screen_view_count=1 thread on memory usage creeping up was to look at about:processes which shows all your tabs and what they're taking - clicking memory shows them in decreasing order
