Bermudan Swaption Demo--Much faster in release mode

[Nehal Patel]

Since I spent some time before I realized this, I thought I would share it with the list... fyi, the bermudan swaption runs about 20-30 times faster in relase mode than in debug mode. 

 

I wonder what causes this significant difference?

compiler optimization are disabled in debug mode.

Inlining is disabled as well.

And finally, in debug mode Arrays are checked before access---although I
don't think this can account for more than a factor 2...
