"per-char" stats are different between different operating systems because of how they are implemented. Apparently, bonnie++ forces full disk writes (fsyncs) for each byte written on BSDs, but Linux (and apparently Solaris) somehow manage to write-cache this (or at least - cache it much more). It only matters if you have software which depends on this caching and performs slowly otherwise. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
