Well, obviously I went a little overboard with my example of a Pentium 4
for a DHCP server! &;-) But I'm still a bit queasy about running DHCP on a
slow server. Selecting a DHCP server requires an analysis of how many
clients ask for services at once, obviously, and how much processing power
that uses. I don't have any numbers. This would make a good research
project and white paper: Scaling DHCP Services. Hmmmmm....
Also, I got to thinking about my other brain-damaged response regarding
leases. If a computer is rebooted, it effectively loses its lease, doesn't
it? The lease time isn't stored anywhere in non-volatile RAM, is it? So, a
rebooted station would contact the DHCP server for a new lease. So for
companies that turn off their computers at night, a large flurry of DHCP
requests first thing in the morning could result in a processing bottleneck
at a slow server.
I work in a school where we do turn off all our computers at night. Maybe
most companies don't, although in California, they probably should!
