Hi !
I wanted to know if someone could help me speed up NFS transfers with FreeBSD-4.7-STABLE.
With Linux clients+server, the transfers are exactly twice faster than with freeBSD, so I am sure I must have screwed the configuration somewhere.
Here are the options used for mounting:
rw,intr,hard,-r=8192,-w=8192,-U
And here is the server's rc.conf:
nfs_reserved_port_only="YES"
nfs_server_enable="YES"
nfs_server_flags="-h 192.168.0.1 -u -t -n 4"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"
Search the archives ... I seem to remember this being discussed in great depth a few years ago.
You may be able to increase the -r and -w sizes to improve things. My understanding is: you should use UDP mounts if the servers are close together (i.e., one hub/switch between them, low latency) but use TCP mounts if they are far apart (i.e. many hops, high latency, lots of dropped packets). I don't know if specifying both -u and -t hurts anything. But definately search the archives, there was a LOT more useful information in the previous discussion. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
