Plase read da1 and da2 instead of sd1 and sd2. I benched the individual drives right after installing 3.4 and was still thinking older device names. Anway, sd1 and sd2 are the drives striped together to get testc. Could somebody please explain why the sequentional block output is sooo much slower on the striped partion than the individual sd1 and sd2 drives? #Bonnie -s 200 /disk1 /dev/sd1 -------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/sd2 -------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 -------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 -- Thanks!
