I am using FreeBSD 7.0-Release (tried both 4BSD and ULE) using AMD64 and the 3ware performance for writes is just plain horrible. Something is obviously wrong but I'm not sure what. I've got a 4 disk RAID 10 array. According to 3dm2 the cache is on. I even tried setting The StorSave preference to "Performance" with no real benefit. There seems to be something really wrong with disk performance. Here's the results from bonnie: File './Bonnie.2551', 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 9989 4.8 6739 1.0 18900 7.8 225973 98.5 1914662 99.9 177210.7 259.7 Any ideas? Anybody have one of these that's working with FreeBSD 7? ____________________________________________________________________________________ Never miss a thing.
