----------------------------------
Hello, I was reading the patch and benchmarks. Very interesting task. Good job.
I believe the performance will increase if you using zero-copy techniques [1].
Here has an example where there is a gain of 65% [2]. Infiniband supports zero
copy through of RDMA [3]. Netty also has support [4].
