[Pdns-users] This can't be right - DNS Load Test Results

[Max Clark]

I recently ran a series of dns load tests against various dns servers
and have been greatly surprised by the results
(http://www.clarksys.com/2007/11/20/dns_load_testing_results/) - in
this test PDNS was slightly faster than TinyDNS and half as fast as
BIND. Because the query set was highly repetitive during the test I
would have expected PDNS to cache the results and serve subsequent
queries from this cache. That does not seem to have been the case
here. I am preparing a lab environment to run additional tests to
validate these initial results and would appreciate any input from the
PDNS community for configuration.

Best,
Max
