[erlang-questions] Erlang zlib and concurrency

I found same problem while profiling the ejabberd server. I wrote a zlib
implementation but unfortunately you can use it in case you want to do
streaming only. As time the interface doesn't expose to many stuffs. We
created it only to cover our bad performances in ejabberd.
But also you can look at benchmark to have an idea how slow is zlib coming
