Windows uses the top of the memory for file caching. And according to ct this gives a big performance penalty on machines with >64MB memory.
Probably it would be a good idea to use memory above 64MB on Triton FX/VX/TX boards (and some others) as _fast_ swap space. (Eg allocate the memory as ram disk and than use it as swap device) Where in memory are ramdisks located?
However, I think this is still broken (as is the idea to use more than 64MB in these machines).
