These days I keep /usr/portage on a separate partition to minimise fs fragmentation. On an old slooow box of mine I have /usr/local/bin and /usr/local/lib on separate disks, as well as /var/tmp and /usr/bin and keep them on primary partitions for extra speed and parallel access/processing across two different IDE controllers: http://tldp.org/HOWTO/Multi-Disk-HOWTO.html One can get really silly at this, I certainly did, but on modern machines with SATA drives the difference in speed is probably marginal. I didn't keep notes of any benchmarks but despite the asthmatic hardware my multi-disk/partitioning scheme did pay some noticeable dividends as far as I can recall. Of course, YMMV. -- Regards, Mick
