Performance of dhcp fail over protocol

[Robert Hille]

We had similar problems when we first tested failover. dhcperf can be a 
pretty abusive test without much tolerance for failures, if there are 
any problems with your dhcp configuration or latency in you netowrk, 
dhcperf will fail horribly.

Once we spent a little time troubleshooting and making sure everything 
was correctly configured, performance can up to near the same as 2 dhcp 
servers.

I'd suggest going back through and double checking your configs and 
making sure that the servers are communicating correctly (and they have 
a clear path to and from the test box).
