Been poking around on my little FreeBSD firewall/server box - think I have Samba to the point where it doesn't hang the network interface (vr0) when sending it big files from a Win2k box. Had to do a "sysctl -w net.inet.tcp.recvspace=32768" and in smb.conf added "SO_RCVBUF=8192 SO_SNDBUF=8192" to the socket options. But even so, it doesn't seem very fast, and still gapped out twice so far.
Seems kind of silly in this day and age to have to futz with things like that - it should just work (at least it has for me on older FreeBSD/Samba combinations). Maybe there's something more deeply wrong somewhere - and the setting changes I made just sort of mask/workaround the problem.
Anyhow, got an iMac at work today - OS X seems very cool. A monkey could set it up and start using it - but open up a terminal window and you see pretty much the same stuff you see on FreeBSD. Kind of a schizo experience. Wish Steve Jobs would get off his hardware obsession and do an x86 MacOS X - sure would like to run that software on hardware that costs 1/3rd as much as that Sharper-Image type stuff that silly graphic artists get all hot for (yes it is nice hardware - but so's a Mercedes, and we can't all drive those)
