I agree. That's really not usefull comparision. They should create categories for each benchmark, like:
- very naive code (shortest, most readable & easy to write code)
- idiomatic code
- optimized code without other-language-libs wrappers and without SIMD, single threaded
- optimized code without other-language-libs wrappers and without SIMD, multi-threaded
- optimized code without other-language-libs wrappers and with SIMD and/or multi-threaded
- optimized code with other-language-libs wrappers allowed and any other optimization technique
