Drogon: The C++ Framework That Tops HTTP/2 Benchmarks (And Where It Struggles)

Drogon, a C++ web framework built on the Trantor async networking library, ranks #7 overall in HttpArena benchmarks and takes first place in HTTP/2 baseline tests at 64 connections with over 10.6 million RPS. While it excels at HTTP/2 and static file serving, it struggles significantly with JSON serialization at moderate connection counts, dropping to near the bottom of the pack before recovering at very high concurrency levels.
