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. Hmm, with such slow machines, network/nfs latency shouldn't be much of a problem. Makeworld of a ~5.2 world with a Turion X2 2GHz takes 14:24m here. About 1m of this time is extra for nfs. It took a bit of work to reduce the nfs overhead from a few minutes (about 5?) to only 1. Bruce
