Might be worth adding zswap using zstd or lz4 to your config (uses more CPU |
16 |
for less IO) |

If you want to see which processes are using the most memory, run top then |
20 |
type 'M' to have top sort by memory instead of CPU. You can also type 'm' |
21 |
to make top show the memory numbers as an ascii bar graph. The man page |
22 |
explains what VIRT RES SHR mean. |
