Message-ID: <28975@cs.yale.edu> Date: 21 Feb 91 20:19:48 GMT Sender: news@cs.yale.edu Followup-To: comp.protocols.nfs Organization: Yale University, Dept. of Computer Science, New Haven, CT Lines: 18 Nntp-Posting-Host: bigbird.cf.cs.yale.edu Is there a magic formula for determining how man nfsd's to run? "System Performance Tuning" by Loukides says "...4 is appropriate for most situations. The effects of changing this number are hard to predict and are often counterintuitive. For various reasons that are beyone the scope of this book, increasing the number of daemons can often degrade network performance." The SunOS 4.1.1 man page suggests 8 nfsd's. What happens when you run too many nfsd's? Too few? In our case, we're running Sun 4/390 servers, typically with 2 1 GB IPI disks on one controller. Each server serves around 20 "sorta-standalone" Sun 4/60 clients (/, swap, and /usr are on the client, /home is on the server). -- Ed Anselmo anselmo-ed@cs.yale.edu {harvard,cmcl2}!yale!anselmo-ed Brought to you by Super Global Mega Corp .com
