I've been on 16GB RAM for about 10 years. I've been using a 4GB swap |
7 |
partition for about 8 years. Two years ago, I disabled swap. This fixed |
8 |
a long standing problem where running applications that I didn't touch |
9 |
for a while would take *ages* to start operating at normal speeds again. |

Setting the vm.swappiness=10 sysctl didn't help either. Only |
11 |
vm.swappiness=0 got rid of those issues (which basically means disable |
12 |
swap.) |

I don't know how common this problem is in general, but for me it |
15 |
happened a lot because I use virtual machines to do work on Windows 10, |
16 |
Ubuntu and macOS running in Gentoo. This always resulted in applications |
17 |
that I didn't touch for a while getting swapped out even though there |
18 |
was plenty of RAM free. Since I disabled swap, everything stays nice and |
19 |
snappy all the time instead of becoming a sluggish nightmare after a while. |
