I did some tests with
1. Knoppix V3.7 2004-12-08 (kernel version 2.4.27)
2. FreeBSD R5.3.
I used the same harddisc slice for the tests (just the *ad1.sh
scripts uses another slice, because I was curious; I do not know
the results). hw.ata.wc was enabled.
My findings are:
1. Linux is much faster with "async" mount (somebody in this
thread already mentioned that yesterday).
2. FreeBSD with soft updates is much faster than Linux with sync
for further details (until 2005-01-27 00:00 Zulu Time (GMT+00)).
Further research is necessary, if I wanted to find out, what
async/sync mount means (especially in the case of enabled write
cache?), or why async mount is much faster...
