As I mentioned in another comment, the minigzip used is very suboptimal due to reading and decompressing only 1 byte per inflate() call. Please retest with --zlib-compat or the fix that was merged today.

Sure thing, updated.
I'm not in the habit of including compression level 6 in the results, since the application I care about defaults to 5 :) And I wanted a good spread of different compression levels in the results.

Btw, I always wondered..
Why didn't you test compression level 6, it is the default level, and used by for example stock apache/nginx settings.
Also #zlib-ng on freenode if you or anyone else want to discuss.
Results with zlib-ng and a newer version of the Cloudflare changes:

Here are some benchmarks of the Intel and Cloudflare forks that this project is based on:

The speedups are not insignificant. (I'll see about updating the post to include results for zlib-ng).
