Re: high performance open source DHCP solution?

hey,

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?

You are doing something wrong:

* turn off ping-check
* use proper raid controller with battery backup (because isc dhcpd does fsync every time it writes to dhcpd.leases)
* ...
* profit
