@GuillaumeRossolini Yeah, I think a better one would be to analyze (rather than score) the standard/extended-standard library where quite a lot of languages ship cryptographic algorithms, json/xml encoders/decoders, http client/server library, …
And I guess measuring the CPU time + memory usage of runtimes for initial launch, threads, `fork()`, idle/sleep, …

Which reminds me of http://bulk.fefe.de/scalability/ which analyses OS and libc runtime.
