If you application seems very slow on todays super fast GHz PC's, that
to me that suggests the application it is doing an awful lot of CPU
Have you profiled your application to check that the appliction is not
wasting time on a badly code algorithm or flow structure? Does you
machine have lots of spare RAM? RAM always helps speed up memory
If you do have an optimal algorithm then your applicaiton is just CPU
intensive and I would be suprised if the any amount of optimazation
would greatly improve the speed.
