>I use m. but, Short of buying a new computer, I am wondering if there are any more ways to speed up code execution?

Remove all the slow parts. :-)

I suggest that you use Coverage Profiler: Markus Egger wrote a tool many years ago to analyze the data generated by Coverage Profiler, but unfortunately I am not able to find any URL where you can download it. But I know it's out there since I downloaded it myself to another machine last year, so you may find it if you search for it. It will help you find out where the bottlenecks are.
