In each case, the first 2 entries are the seperate drives. Then comes the vinum volume, testc. I ran striping at 128b, 256b, 512b and 1024b. In all cases, vinum absolutly dies in the sequential write, at least in my case. Any comments? first is the conf file. ------------------------------------------------------------ drive drive1 device /dev/da1s2e drive drive2 device /dev/da2s2e volume testc plex org striped 1024b sd length 5169m drive drive1 sd length 5169m drive drive2 ------------------------------------------------------------ root$ rawio -av /dev/da1s2e Random read Sequential read Random write Sequential write ID K/sec /sec K/sec /sec K/sec /sec K/sec /sec anon 709.9 44 44065.0 2690 877.6 54 6575.6 401 root$ rawio -av /dev/da2s2e Random read Sequential read Random write Sequential write ID K/sec /sec K/sec /sec K/sec /sec K/sec /sec anon 707.9 44 49995.6 3051 931.5 58 6818.3 416 root$ rawio -av /dev/vinum/testc #128b Random read Sequential read Random write Sequential write ID K/sec /sec K/sec /sec K/sec /sec K/sec /sec anon 1082.3 67 40147.9 2450 1031.1 64 1944.5 119 root$ rawio -av /dev/vinum/testc #256b Random read Sequential read Random write Sequential write ID K/sec /sec K/sec /sec K/sec /sec K/sec /sec anon 1090.6 68 37885.9 2312 1006.4 62 1946.2 119 root$ rawio -av /dev/vinum/testc #512b Random read Sequential read Random write Sequential write ID K/sec /sec K/sec /sec K/sec /sec K/sec /sec anon 1112.6 69 38752.4 2365 1009.6 62 1948.3 119 root$ rawio -av /dev/vinum/testc #1024b Random read Sequential read Random write Sequential write ID K/sec /sec K/sec /sec K/sec /sec K/sec /sec anon 1129.3 69 38876.6 2373 1000.1 62 1942.4 119 Bonnie -s 200 /disk1 /dev/sd1s2e -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 200 7510 93.4 8428 21.5 2856 15.8 7485 93.2 11164 27.4 227.0 6.3 /disk2 /dev/sd2s2e -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 200 7546 92.4 8403 21.6 2871 15.9 7512 93.0 11375 29.6 199.9 5.9 /testc /dev/vinum/testc 128 blocks -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 200 7862 95.8 2720 26.3 5495 30.6 6129 74.9 22002 65.6 319.7 9.6 /testc /dev/vinum/testc 256 blocks -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 200 7835 95.2 2774 26.9 5890 31.9 6299 77.0 21613 65.2 311.8 9.4 /testc /dev/vinum/testc 512 blocks -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 200 7881 96.3 2886 25.9 5765 31.7 6297 77.0 16289 46.5 315.8 9.6 /testc /dev/vinum/testc 1024 blocks -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 200 7863 95.7 2873 26.4 4058 23.2 6273 77.5 13422 36.0 312.0 9.5 -- ========================================================================= UNIX IS user friendly, it's just very choosy about who it calls a friend! ========================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
