I think y’all should consider the benchmarks to date as prototypes. Tonight I wrote some scripts which will make my tasks easier and faster. It’s great not to have to manually enter all the commands. It also makes for consistencies between each run. We’ll concentrate on just two tests: bonnie++ and fio. These tests will be performed on both ufs and zfs. I’ll also run the tests on the drive when attached to
