When I was on gentoo I was using 9gb of ram as a ramdisk to help speed up compilation. You mention temp if its on the same disk aren’t you going to have no gains in performance like that?<br> > <br> My reasoning was "it can't harm and might help". If /tmp is tmpfs then<br> it gets cleared out every boot. Saves wasting space. And<br> /var/tmp/portage was tmpfs for the same reason - if the system crashed<br> during an upgrade it would have caused a bit of a problem but otherwise<br> it's fine.<br> <br> Where is your swap? Is that on the same disk - do you only have the one?<br> A tmpfs stores everything in memory - ram+virtual - so if it runs out of<br> ram it overflows into swap. I just wanted the space available if it was<br> needed.<br> <br> Bear in mind also that if you make heavy use of tmpfs, then with gentoo<br> it probably never touches the hard drive - it's downloaded, exploded and<br> compiled in ram all the way. On Fedora, it'll be slower because it needs<br> to be pulled from disk by the compiler. And a ramdisk won't help because<br> you've got to copy it on to the disk ... :-)<br> <br> I'd just trust linux to do the best with what's available, and don't<br> expect two very different distros to behave similarly.<br> <br> Cheers,<br> Wol<br> </div> </span></font> </body> </html>
