The benchmarks say "to make 1000 HTTP requests", but I wanna know for sure if it was `https` (SSL) or not.

The SSL connection init costs are real, although SSL session re-use can help there even without keep-alive.

These metrics were collected for HTTPS specifically. I've omitted the URL I used in the benchmark scripts, but am using an HTTPS agent. Scripts live here: https://github.com/mgartner/node-keep-alive-benchmark
