Thanks Amnon for the insight, which confirmed my guessing when answering the following question against ab in my blog:
> I'm unclear how to interpret the results from ab. From the top chunk of the > results (time taken for tests, requests per second, time per request, etc.), > it would appear that Go is about 33% faster than Perl. But the bit at the > bottom about "percentage of the requests served..." seems wildly incongruent > and makes it look like Perl is orders of magnitude faster. It doesn't add up. > It also doesn't logically add up for Perl to be faster than Go (which, I get, > is your point). It makes me suspicious of ab's results.
