I don't know about vadvise (or many other swapping heuristics). I remember a nice (easy) way to speed up PROLOG about 30% is to mark pages of garbage as garbage so they are not written to disk. PROLOG (and LISP) use lots and lots of stack space which is frequently freed. If You don't mark the pages as garbage, your computer will write an essentially blank page out to the disk. Later, it will read in this same blank page. If it was marked as unused (garbage), a couple of swaps can be saved. -Marc Milgram
