Thanks for helping out with large scale testing of the patch! Did you compare the accuracy of the 16,384 reverse-resolves (e.g. what percentage succeeded, since it sounds like they all should have in an ideal case) between the patched and unpatched versions? Performance alone only tells half the story. Cheers, -F
I considered that but it looked to me as though both were > 99% accurate. I wanted to get some results emailed before I went to bed and the results weren't fresh in my mind. I'll re-run the non-patched tests to check accuracy.
