Earlier PSGI server benchmarks
I searched the interwebs for PSGI/Plack server performance comparisons but did not find any which included uWSGI. It looked like the benchmark in the Starman documentation is the only one available and quoted in many places. It declares Starman as the fastest PSGI server: Continue reading
