My suggestions are so basic that I fear I may not understand your question. Anyway, the two techniques are 1. buy more memory. At some level of memory, you won't ever page or swap. 2. Set the sticky bit on your application. This can decrease system performance if it leaves insufficient memory for other essential processes. -- Tom Reingold tr@samadams.princeton.edu OR ...!princeton!samadams!tr "Warning: Do not drive with Auto-Shade in place.
