Might be worth adding zswap using zstd or lz4 to your config (uses more CPU
for less IO)

If you want to see which processes are using the most memory, run top then
type 'M' to have top sort by memory instead of CPU. You can also type 'm'
to make top show the memory numbers as an ascii bar graph. The man page
explains what VIRT RES SHR mean.
