Completely unnecessary, linux is already smarter than this. All otherwise unused ram is used for block caching. All recently read blocks are stored in RAM, this includes programs, data, everything. Beware, I was having overheating problems a while back, when I upgraded to 512mb RAM, ~256mb was used for cache, that means you can loose a LOT of data if your machine hardlocks for some reason. If you're hardware's at all flakey or you're playing with a new untested kernel driver, get in the habit of typing 'sync' a lot... _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
