24 TBH, unless you are really stressing your RAM usage (Lots of VMs or Java
25 applications, stuff like that) I'd go without swap. I've been running
26 swapless on 8GB of RAM for a number of years now with no issues.
28 As for /var/tmp/portage on tmpfs, this is fine 95% of the time, however
29 even with ~2GB I allocate some packages (Chromium, LibreOffice, ect)
30 will fail to compile due to lack of space. In these cases I just
31 un-mount /var/tmp/portage, do the compile on the disk, and then re-mount
32 it.
