Hi

This mail list is for ISC Dhcpd, which runs on Unix and Linux systems
(there may have been a port to the Cygwin environment to allow it to
run under Windows). Anyway, most people don't run Microsoft DHCP, so
suggest you try a different forum if you want an acurate answer.

With ISC DHCPD users report >200,000 users on regular server level
hardware (2-4 cpus, 2-4GB memory, fast disks). I don't know how
efficient MS Dchcpd is, but would guess that a server with those
specifications should handle 5000 clients.

The main factor affecting performance issue is lease times. If you have
short lease times (less than a few hours say) then the rate of lease
renewels will be proportionally higher than if you have long lease
times (like a few days).

eg 500 clients renewing every hour is about the same rate as 5000
clients renewing every 10 hours.
