To: questions@freebsd.org Date: Fri, 15 Mar 1996 11:57:51 -0500 (EST) From: "Jeff Wheat" X-Mailer: ELM [version 2.4 PL25 ME8b] Content-Type: text Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi, I'm trying to increase the poor performance of my NFS servers. I've tried to use the TCP type mounts, and tried using r=8192 and w=8192 to no avail. The present stats I get are: -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU nfs-mount 1 106 5.8 123 2.2 132 5.3 567 30.5 5988 92.2 127.3 27.2 -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU local 1 1143 93.1 2216 84.7 1762 92.4 1893 94.3 6349 100.0 579.2 81.3 These benchmarks are very bad as you can see. What can I do to increase the performance of my mounts? Any help is greatly appreciated.
