Where do you get that ISC DHCPD only handles 200 DHCPDISCOVER / 20 DHCPRENEW
requests?    That doesn't sound right.   So I wonder what are you measuring?

Is this a number of answers per second your implementation of ISC
DHCPD is providing successfully?
There are architectural facts about any environment besides what
software is performing the DHCP task.

How many  I/Os  + fsync()'s  per second can this DHCP server handle
that does only 20 renews?
