No. I haven't used it in a while, and it was always over SSH from my
machine. When I did use it to do a render it was usually at night or
running with a very high nice level.

BTW, Jacks response mentioned adding -m64 to the command line. I don't
need that since I'm running the all-64-bit AMD64 Debian port and gcc
generates 64-bit binaries by default. You'll have to check what your
distro has set up.
