Hi,
When looking at the QPS benchmarks <https://grafana-dot-grpc-testing.appspot.com/?orgId=1&from=now-30d&to=now> (and reproducing them) the performance gap between the C++ and Go is more than x2 (Go is faster). The test scenario appears to be quite similar: Streaming secure throughput QPS (8 cores). I tried to look deeper into it and found that C++ server has lots of outgoing small TCP messages (~100-200 bytes). These appear to take a considerable amount of CPU time. When Go server was considered, the number of small messages was just a bit higher than the number of large (~1.5Kbytes) outgoing messages. I wonder if anyone has explored this and if there are any directions (or maybe existing implementations) for improving the short message performance of C++?
