I've only been watching this thread with half attention ---

DHCP is UDP based -- as such it does not handle collision 
retry logic on the server side (a server cannot resend what it 
does not know [due to a collision and drop] a client has 
requested of it)

So client retries are in play -- the ISC dhcpd server is able 
to handle loads substantially above the rates quoted per 
minute

I've had setups involving LTSP PXE booting of diskless 
workstations, supporting several hundred such clients all 
booting within 5 minutes of one another at a shift start

It is necessary to model, or perhaps view with tcpdump of 
ethereal, that traffic to see why the transfers are falling 
apart
