Dear John and Daniel, I can give some speed-up advice if you show me what type of integrals you want to integrate numerically. In general. tuning the NIntegrate's options Method, SingularityDepth, MaxRecursion, MinRecursion, for a particular integral might give faster convergence. Anton Antonov, Wolfram Research, Inc.
