I've done high speed data collection on a micro-vax.  It worked okay.  The
problem isn't VM, but not having enough real memory.  The micro-vax I was
using had enough memory so it wasn't page swaping all the time.  A well
writen VM system won't slow you down when you have enough memory, and it'll
let you use more memory then you have when you need to.  You should only be
getting a noticable speed drop when you are using more memory then you
really have.  I'd rather use a big application slowly then not be able to 
use it at all.
