The last days I tried to figure out why some of my lab's FreeBSD boxes
and also mine at home seem to be outperformed by some Linux setups
around here and I saw something interesting.

copy process via 'systat -vmstat 1' and realized, that the value of 'KB/t'
never go byond 128 (128kb buffer limit?). But more frustrating, I never got
what's wrong? FreeBSD uses 128k limit by default.

you can change FBSD to async
then watch your fs scramble during a power failure
no big deal, it's only your data.
you are wrong, he talked about copying BIG files, and this shouldn't make
a difference contrary to small files.
there is something wrong there as i routinely get 70MB/s on my

Also, you should time the actual copy and do the math to verify that

in vmstat or the underlying statistics it uses.
There is certainly a bug in the underlying statistics. For ATA
