"fast enough" is subjective, for some people NodeJS is "fast enough", for some other people python is "fast enough"
cheating in benchmarks i guess is part of the job at these big companies, gotta find ways to justify your huge salary i guess
One could say that:
In the "fortunes" category, the giraffe F# benchmark, which is a single 150 line file used 100% as advertised in the documentation performs better than many java frameworks, some CPP frameworks, etc: https://github.com/TechEmpower/FrameworkBenchmarks/blob/mast...
However, that's not accurate. It's an incomplete take based on a fragment of the data. It's a matter of data presentation and sympathy/empathy with your audience (IMHO).
