I'd pick on a different statement in regard to this test: This is a disk and filesystem benchmark. It measures the raw disk throughput in several contexts (byte by byte I/O, block IO, input, output and rewrite performance; creating and deleting files). Getting any meaningful results from bonnie++ is a matter of reading entrails. It's almost useless for comparing Linux and BSD, since it uses features of each system which are unrelated to the disk drivers. In fact, it's very difficult to measure the raw Linux throughput, since there are no raw devices by default, though a kludge called rawio is available. Greg -- Note: I discard all HTML mail unseen.
