I have a wide variety of storage devices, and I suspect most of them are underutilized. To make the best use of them I'd like to measure what their actual performance is: disk IOps per second.
The storage is SATA, SCSI, and iSCSI attached to Linux and/or FreeBSD, UFS and ext 3 or 4 on a variety of i386 hardware. I'm not especially interested in which ones /should/ perform better, I want to measure which ones /do/ perform better. (And so I can tell my applications team that they are hallucinating when they blame performance on the file system.) What tools can I use to measure disk performance? -- Perfection is just a word I use occasionally with mustard. --Atom Powers-- _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
