Q: any benchmarks/comparisons?

[4ntoine]

Hi, Cap'n'proto is advertised as a fast serialization protocol. Are there any benchmarks or comparisons (especially with protobuf (original impl and square wire impl)? Thank you.

A bit of background

I'm looking for some protocol/impls to pass the data between C++ and Java considering it as a faster alternative to JNI. See the repo. The mains concern is about serialization performance on Java size, so the protocol can be good, but Java impl performance also matters.
