I don't have the actual benchmarks at hand, but Byron and I discussed 
first-cut performance results. Doing some very DNS-heavy processing 
(i.e., each request was associated with a different DNS record, so no 
caching was possible), I think he said that we were able to push almost 
twice as many SIP transactions through repro with c-ares than with the 
built-in ares.

Normal disclaimers apply (we may have overlooked something, YMMV, etc).
