We are running isc with over 200,000 static host entries. It works
like a charm and is the system that we have had the least problems
with (no problems that I can recall in the past 6 years at least).

 cat dhcpd.conf | grep fixed-address | wc -l


Not boasting for us, but for isc! Great dhcp, great mailing list.
