I'm testing grpc trancode plugin, and find the benchmark result is not in my expectation.
I use perf to generate a flame graph, which shows the nginx upstream connection is not reused...
I have configured keepalive and keepalive for upstream, grpc_socket_keepalive is on.
So... my question is how to keep the upstream connection reused? Many thanks.
