Well, ok, but I still want to get the fastest array available at this moment and I yet only have one array working with Hugs. If you know a way how I can implement that it in GHC, I would be pleased to hear it.
Well, you can use boxed or unboxed IO Arrays. Unboxed will be faster (depending on what you're doing, around 2-10 times faster). A boxed array means that if you have: IOArray Int Int then this is essentially represented as: int* array[] where each array element holds a pointer to the int. Unboxed means that the array holds the actual elements. Obviously unboxed arrays are strict. They're significantly faster though. You should be able to just use the code you were using in hugs in GHC and it should compile fine. - Hal
