Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-hackers@freebsd.org Precedence: bulk Adjile RAID box, 5 Fuji 4GB disks, RAID 5, verify off (on cache), 8MB cache. P5120, 64MB RAM, FBSD 2.1 stable (supped 1/21), Adapter 2940UW, tag enabled. Unfortunately, I was not able to re-newfs this box, and as such, the file system was moderately filled (news partition). When fsck'ing and running iostat, sps bounces between 10k and 13k, which is pretty quick. bonnie: news# bonnie File './Bonnie.629', size: 104857600 Writing with putc()...done Rewriting...done Writing intelligently...done Reading with getc()...done Reading intelligently...done Seeker 1...Seeker 2...Seeker 3...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 100 2249 80.1 2200 18.1 1290 16.9 2467 76.1 4503 28.3 65.9 5.5 iozone: Writing the 150 Megabyte file, 'iozone.tmp'...69.906250 seconds Reading the file...36.132812 seconds IOZONE performance measurements: 2249961 bytes/second for writing the file 4353007 bytes/second for reading the file
