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.<br>
<br>
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.<br>
<br>
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).<br>

Hi<br>
<br>
I have fail over running on 3.0.5 , if i run dhcperf on the fail over configuration the Performance numbers are abysmal . The average transactions per second is less than one.<br>
but on a standalone i am getting 42 transaction/sec. Do we have to compromise on the performance if we have fail over configured. I am not sure whether i am doing it the right way but the fail over is working properly and the server is able to allocate the leases. I am not able to understand what causes the server performance to do go down so drastically . Is it because of the frequent primary secondary communication ? or is there any timer which we can modify to improve the performance .? any help is appreciated .<br>
<br>
