It could very well be. There is a lot of difference between debug and 
release builds in places that do complex maths operations.. like ODE. I 
wouldn't be surprized if the speed ratio was around 5-10, instead of the 
usual 2 in a "normal" program.

In addition, what kind of space are you using to store your geoms in ?
