For this it's essential to use the multiple cores the hardware provides. 
So the task needs to be distributed to multiple threads.

I once drafted a thread pool unit that night be useful for this (but I 
suppose there are other tools that are much more decently tested than 
the one I did).

In the FPC/Lazarus mailing lists there already were multiple discussions 
on the "parallel loop" issue, but AFAIK, there is no ready-made solution 
available yet.

Delphi XE claims to provide such support, though.
