Today Debian dropped 64 updates on me, and while I was installing them I noticed the /var partition was at 95%. As luck would have it, my IP address changed during my last hardware emergency and I had hard-coded the address in the cron job that did the Proxy Project backups.
This is not the first time this has happened.
So now I'm moving all those backups and I'm getting stunning performance copying the files.
It has taken me years to get this kind of SMD/CIFS performance out of Linux. Maybe it's just my choice of NICs. I've been using RealTek NICs forever and this box has an AMD. Maybe it's the 64bit platform. The last AMD64 based system I had—before it died—was similarly perky.
It's probably time to upgrade to a gigabit network. That way, even crappy performance is better than 100 megabit.
