Hi Clinton,
I can also confirm that the patch appears to work correctly on Mac OS X. I tested with this patch and with the "quick distance calculation v1" patch also applied.
On a 2 GB, 2 GHz Intel Core 2 duo machine, a combined map of France, Germany, Switzerland, and Italy took about 45 minutes to compile. Without these patches, it took about 1 hour and 40 minutes.
Good, that's a x2 speedup.
Sorry, I didn't test the patches separately, so I don't have data on the individual performance improvements.
Don't worry about that, I am more concerned with correctness at this time.
At any rate, with superficial testing, both patches seem to be stable. Thanks!
That's good. If you're happy to keep using the patches, please do and that will give you a chance to spot any problems. Cheers, Mark
