Look at my dd-test: Linux fBSD fBSD with async (linux with sync) dd-test 2.61 4.95 4.78 2m06 (!!) also with the other tests fBSD is still slower and the sync is faster, even faster than last time without async, so FreeBSD really wrote everything already. and I'm sure the / was mounted with async! (checked with mount) i'm using an i486 with 40mb's of memory so that should be enough for FreeBSD to do something :-) -= Paul =- P.S. ext2 with sync mounted is terribly slow! Comparing that with fbsd, fbsd is faster in writing really to disk.
