The free DHCP solution, ISC, seems to be having scaling issues (i.e. handling only about 200 DHCPDISCOVER and 20 DHCPRENEW requests), and I was wondering if anyone had any open source suggestions of solutions that could scale much better? (Ideally, I could find a free version of a solution like Nominum, but I know that's asking for much.) Anyone have any suggestions? -- Also on LinkedIn??

[CentOS] high performance open source DHCP solution?
>Anyone have any suggestions?You thought about using its built in load balancing to scale out the capacity? Don't know what hardware you are using but it might be worth looking at the lease db and log file setups you are using if you can't add iron to the equation.

What kind of hardware and how much RAM does the server have? My first thought would be to use a 2nd system which you probably want for failover in any case. -- Les Mikesell lesmikesell at gmail.com

Have you asked on the ISC DHCP mailing list? They'll know best how to tune it for your load.
