thanks for measurements, it's good to see.
i guess couple of reasons here.
- because we compress short packets with IPComp, we cannot make a good
use of compression history/dictionary. we always initialize
everything on every packet, and it can consume cpu time.
- zlib buffer management - it has ring buffer management on both
in/output ends, because we will see data stream with different sizes.
- zlib memory management - heavy use of malloc?
