The results in the tests are all with optimisations (-O3 -march=sandybridge -mtune=intel), as mentioned in the post.
The exception is the Debian packaged version of zlib, because we don't control that. That's the reason I include stock zlib in the tests - if it had been wildly different from the system zlib, I would have looked into recompiling the Debian package with more optimisations. There were no major differences and indeed, inspecting the package further shows that it is compiled with optimisations.
On the Cyrus side, we used to link to the Debian zlib, so we get those optimisations. For the new code bundled in Cyrus itself, we have to enable optimisations ourselves.
