Mr. Silbersack, thank you very much. you've restored my
systems to their pre-4.3 stunningly fast behavior.
to the hackers group, i apologize for polluting the air waves with
my original plea for help.

for my money, hw.ata.wc=1 soft updates OFF is a better performing
choice than hw.ata.wc=0 and soft updates ON.
(soft updates are great, but i really dislike the performance
stalls that it (or async mode) engenders with big copies/etc
for other processes).
if the freebsd group still chooses to keep hw.ata.wc=0 as
the default, i would urge perhaps a different mode for base
system installs. the reason i used '8192m' partition in
my original mail was because the wait for a 60gig newfs was
pretty painful.
in my original message i made a reference to linux.
i'm a die-hard freebsd fan, but for work reasons etc i take
a look at linux from time to time. in the same system that
i mentioned originally, i've tried the experiment of powering
off a machine (with no halt) after the first reboot after
a virgin suse-7.1 install. linux couldn't put itself back together
without manual intervention - the fsck seemed to just freak.
even with the historic hw.ata.wc=1 effective mode of freebsd-*,
i've never seen such bad behavior as i had with the linux-7.1
system.
THANKS again to all you folks for the outstanding performance
and reliability that freebsd attains.
