: Ok. To answer my own mail. A buildworld with a local /usr/src takes 2:50h
: on that machine, with /usr/src on the W2003 server 3:50h. Looks not that bad.
So we're talking 33% slower here rather than 90% slower that I see for
my entire product build. So the speed is similar to what I've seen
over NFS here...
