It's important to fully understand what the Linux free command means. Linux uses as much memory as it can as disk cache, should a program need that memory Linux will immediately drop that disk cache and free the memory for the running program so when you look at the output of free, subtract "cached" from "used" to get a better idea of the available ram for programs. "free" is only that part that is completely unused (i.e. wasted). So it's a good thing that it's only 5 megs as long as cache is high and there's plenty of available memory. What's likely happening here is Linux is caching your folder files which is a good thing as it's likely you'll be reading from that file again. UW-IMAP has some performance problems of it's own though. Be sure to look at the SM documentation on speeding up UW:
