Hi Marc,

Is there a document anywhere that describes how to performance tune Gambit ? I've been writing some genetic programming code which Gambit has been great for for small examples but now I'm running into severe performance problems.

I'm tryin to load a large CSV file of approximately 40MB into a list of records but I gave up on it when it still hadn't finished after 30 minutes. When its loaded, I'll need to iterate over the full set around 500k times which I'm expecting taking a while but hopefully no more than a couple of days. I'm using the interpreter at the moment so can try compiling but is there anything else that I can do ?

1. Compile. Profile. Use better algorithms. 2. Use declarations, typically (declare (standard-bindings)(extended-binding)(block)(not safe)) (if these are applicable) and flonum and fixnum-specific operations (also if applicable) Brad
