Well, SMP (Symetrical Multi Processing) won't make any one process
faster than on a Uniprocessor system. What it does do is make the overall
system throughput faster, 'cause while one processor is busy, the other can
be performing other tasks.
If you're strictly using it for personal use, you'll probably not
see much difference. If it's a server, you may well see a lot of
improvement. Samba, for example, forks an smbd for each connection. These
can run independently, and on seperate processors, for an overall speedup.
NFS forks a number of processes (nfsd being the "work horses"), and will
benefit.
Finally, I don't believe VMWare supports SMP in the guest OS. Not
yet, at least.
