I know what swapd and swap priorities are (I think I do, OS thing and how partitions are used). I am speaking about something that "owns" a partition (or filesystem or warp generator) and accepts request from apps like "hey you! move this are of my RAM to your storage" and "quickly! give me back the data I give you some minutes ago". So Gimp could use it, instead of using OS things (swap or filesystem). I guess everybody will agree that a partition handled by one process (with high performance in mind) is a good solution. Well, now you can point why my suggestion is 100% wrong. ;] >> I think that is what high end DBs do, handle their own data physical >these high end db's also do not recommend this technique ;-> Really? Maybe time to get a book about DB implementation. Damn, so many thing, so few time. GSR
