But, I'm only ever comparing times on the same system, and this package (abiword) was almost at the end of my build, so the amount of '/' used is almost the same (for me, /home is always a separate filesystem - ok, I've probably extended the usage of /var/log - and yes, updating the browser cache involves head movement, but such a large variation ? > > If thats the case then using an SSD should improve the relyability of > build times.

Multiple cores ? I'm using single-processors from somewhere between 4 and 5 years ago ;) ĸen -- for applications, 31 bits are enough ;) -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
