We did a head-to-head comparison of:
PC (PII 350 MHz, 256 MB RAM, running FreeBSD)
vs.
Sun Ultra 10 (320 MB RAM)
doing a typical SPM of a PET dataset.
Guess what? The PC was faster by a factor of 2.
Note that you will have to do a bit of hacking to get matlab and spm
working properly under Linux, though several listmembers have done so.
We went with FreeBSD because it's apparently a bit faster for
networking. FreeBSD has a perfectly good Linux emulator, and I
run the Linux version of Matlab with all the mexlx files for spm.
