one note though: every study i've seen of nfs activity (including my own multi-month monitoring of a net i ran) shows 1) most DATA is for read (last time i checked read outnumbered write by over 10 to 1) 2) most of that read data is to read only file systems (/usr/local, etc.) (think of emacs, frame, your favorite cad system, etc.) 3) most PACKETS are lookup/gettatr, again to read only file systems so you can win a lot by simply running CFS (from sun) or other caching file system. I have a caching file system for nfs i wrote a number of years ago (Autocacher) but it needs work. Anybody want to do the work, you can have the code. It consists of a modified AMD. ron Ron Minnich |Like a knife through Daddy's heart: rminnich@sarnoff.com |"Don't make fun of Windows, daddy!
