Four core Intel i3 at 2287 MHz. 4 GB RAM. "free -m" says swap is 34 GB with 6.2 GB or 18% in use at the moment. The 'Swap" graph in GKrellM is at about 10%. Who is right? "free -m" says 3542 MB RAM out of 3783, or 93.6% in use. The "Mem" graph in GKrellM is at 50%. Who is right? Top memory users are firefox-esr at 220 MB + 100 MB shared, Evolution at 170 MB with 39 MB shared, KDE plasma shell at 79 MB with 26 MB shared, Xorg at 20 MB with 25 MB shared. The rest are in the weeds. At less than 700 MB, these don't come even close to adding up to 3542 MB. Is the rest filled with disk cache buffers? The symptom remains that if I kill firefox and restart it, things run a lot faster for a few hours, and then bog down again.
