Dear Andreas,
Yes, currently, Matlab is still a 32-bit application and is not a multi
threading software.
We speed up our SPM processing by running 2 SPMs on a dual-processor
Linux machine simultaneously.
Moreover, fast 15000-rpm SCSI hard disks will also help.
You can compare your Mac with an AMD (1800+ Dual) Linux machine by
typing "bench" in Matlab 6.5.
Cheers,
Witaya Sungkarat
