:That's exactly what I expected. It needs almost no processing in
:userland, a little bit more in the kernel to push the IO through the
:various layer and most time waiting for the ATA controller. When you
:repeat the same process with softdep, it should be a lot faster, since
:it can write out many requests ordered. It would be even faster with a
:proper disk scheduler, but that's (still) a dream.

It is clearly an issue with the disk, but 20 minutes is still
a very long time. It takes less then a second on my test box if
the previous buildworld's files are still in the cache. But even
without the cache it should certainly not take more then 30 seconds or
so, and I can't imagine it taking more then 2-3 minutes on an older
system with a slow disk.
