I've used grpc-netty-shaded instead, if that's what you meant, which serves my purpose but increases the jar size slightly (0.3MB) in case that's a problem for you.
It looks like grpc's shaded netty is larger than deep's shaded netty.

@LMarkie that was originally what I thought yes. Could you revert that last commit for now though. I initially missed the comment about the performance being fixed in 4.1.96.Final.
