Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Client is a Digital Prioris HX6000, P6-200/512cache, 32MB RAM, SMC 100Mbit ethernet. Server is a Network Appliance F540, 100GB disk, 8MB NVRAM, 128MB cache, 100MBit ethernet. I tried both TCP and UDP mounts, version 3 and version 2 NFS. The best performance was UDP version 3, for what that's worth. # iozone 500 Writing the 500 Megabyte file, 'iozone.tmp'...86.304688 seconds Reading the file...90.789062 seconds IOZONE performance measurements: 6074849 bytes/second for writing the file 5774792 bytes/second for reading the file using 64k block sizes resulted in about a 4% perf increase, however, it dropped CPU utilization on the Netapp from 100% to about 65%. Here's some bonnie numbers as well. Note that for bonnie, the best combo was UDP version 2, rather than version 3. Wish I knew why. In a nutshell, almost as fast as the fastest single spindles. # bonnie -s 300 File './Bonnie.4599', size: 314572800 Writing with putc()...done Rewriting...done Writing intelligently...done Reading with getc()...done Reading intelligently...done Seeker 3...Seeker 1...Seeker 2...start 'em...done...done...done... -------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 300 5471 62.4 5810 12.9 1104 3.1 4471 52.1 5895 7.5 233.5 10.1
