Understood not sure if it’s tmpfs but I have everything on a single disk. I have a 4th gen i7 in this laptop but what I can’t understand is why even with ccache takes about 2 hrs to compile

If /tmp is tmpfs then it gets cleared out every boot. Saves wasting space. And /var/tmp/portage was tmpfs for the same reason - if the system crashed during an upgrade it would have caused a bit of a problem but otherwise it's fine. Where is your swap? Is that on the same disk - do you only have the one? A tmpfs stores everything in memory - ram+virtual - so if it runs out of ram it overflows into swap. I just wanted the space available if it was needed. Bear in mind also that if you make heavy use of tmpfs, then with gentoo it probably never touches the hard drive - it's downloaded, exploded and compiled in ram all the way. On Fedora, it'll be slower because it needs to be pulled from disk by the compiler. And a ramdisk won't help because you've got to copy it on to the disk ... :-) I'd just trust linux to do the best with what's available, and don't expect two very different distros to behave similarly. Cheers, Wol
