Only thing it might do is allocate a continuous block of memory and force existing programs using memory to be paged, thus reducing fragmentation for any new programs that get opened and use memory. I suppose it could possibly speed somethings up in certain scenarios, but it will most likely slow down currently active applications. On modern computers with 8+ gigs of ram, it will probably not do anything at all, since 64 megs will likely be available. Seems like something that may have been useful on old versions of windows on old machines with 64-128 megs of ram.
