Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Well my NFS reliability at work has gone way up, to the point where we are now having time to look at the finer things in life, like performance tuning. Performance on reads has been quite good, but when the cgi scripts that the users are running on these machines have large writes to do (like re-indexing a database) the writes go really slow. So slow in fact that they sometimes time out, the CGI engine dies, and the job is never completed, causing it to be restarted by the user. So, the big question is whether there is anything we can tune to speed up the writes. The freebsd machines are NFS clients to the sun servers doing most of the web processing. Overall performance on the reads seems to be best with nfs v3 over udp, which is what I'm using now. All of the web server directories are soft mounted directly, with no amd currently in use. thanks, Doug To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
