use the Debian/Ubuntu patchset, which is what I will look at more closely
now. I suspect that maybe one of these patches changes something that
affects performance for small data sizes. Is there some documentation
available somewhere which patch changes what specifically?
I don't think there would be very many patches that are meant to improve
performance in our patch set (note, I did not check). However, the details
of what each patch changes should be in the patch description as well as in
debian/changelog. You may also which to check what are all the compiler
options coming from dpkg-buildflags used in the build... So if what you are
trying to do is build your own copy of openssl to enable a particular
feature, I would suggest using the source package as a base and using
debuild / chroots / PPAs to build your custom package, that way you'd
benefit from the same performance unless your custom changes impact them in
some way, with the least amount of effort.
