Why do you need NFSv3?

What is the speed of your network? > Mounting via TCP gives us 2.5Mb/s. (Is this safe?) Why are you using TCP? If you are on a reliable LAN, use UDP. TCP should be used for long haul NFS. There are lots of reasons for using UDP, if you want me to go into them, I will. > Are there any other possibilities to increase the writing speed (by means > of tuning NFS...)? Again, try UDP. Also, go pick up the O'Reilly book on NFS and NIS. Alot of what I'm going to tell you is in there (indeed the book is on my desk at work). -gordon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
