I'd like to comment on the last entry in the ticket:

For 100% clarity, this was observed with the version of ab shipped with
2.2.34, or the version shipped with 2.4.24? It should be obvious that ab
has also undergone some enhancements and changes for support of TLS, and
the two different versions are expected to produce two different results.

It shouldn't matter which version was used as long as the same one was
used for both tests.

According to the ab output, Paolo used the same version for both tests:

This is ApacheBench, Version 2.3 <$Revision: 655654 $>

Unfortunately this output is useless unless you know the revision
numbers by hart. It looks like it is a 2.2 version, but I could be
wrong. (A 2.4 version has a revision around 1826891.)

Note to devs: it would be great, if ab could use the same version
numbers as the server. ;-)
