Howdy...I remember doing some very unscientific speed test a few years  
ago in deciding that the small bump the complexity of caching. I  
wondered about this the other day, actually. How could it not help a  
lot? In practice, all of that reflection must be expensive.

So, how much speed increase did you get an what can you tell us about  
the nature of your problem?

I'm not familiar with that. can you tell me more about it?
