WebMathematica will be considerably faster and more powerful if you do that. Useful functions are Map[], and related functions. Also Nest and NestList will repeat operations. Many functions like RandomVariate will naturally produce a list of samples. (which can then be processed as a list and not used in a loop). I hope this helps.
