Anything I can do memwriter/mem-balancing wise to help things?
qmemman / meminfo-writer setup things to avoid swap usage, this is intentional. How it works is documented here: https://www.qubes-os.org/doc/qmemman/ If you really want to change this, try /etc/qubes/qmemman.conf - especially cache-margin-factor. You can try setting it to something less than 1.0. But don't be surprised by some out of memory errors later... - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.
