Performance issue...

It seems that TGB is, by default, compiled with "TORQUE_MULTITHREAD" defined. Sadly, there are two problems with this:
1. TORQUE_MULTITHREAD isn't check properly over all of the code. This causes mutex locks to be taken / released on many classes.
2. The platform mutex is using the Windows mutex kernel object which is very slow. I'd suggest converting this to a critical section for better performance.
I've fixed these two issues on my local source for TGB. I've received a 200% increase in list-heavy operations once TORQUE_MULTITHREAD was removed and all mutex code was changed to respect that.
Just some food for thought... if you're doing lots of SimSet/SimDictionary manipulation in your code then this could be a problem for you as well.
