Benchmarks "Google has released a research paper that suggests C++ is the best-performing programming language in the market. The internet giant implemented a compact algorithm in four languages - C++, Java, Scala and its own programming language Go - and then benchmarked results to find 'factors of difference'."

Performance characteristics not the result of language syntax so much as the implementation of the compilers and supporting libraries.

Certain language characteristics have obvious performance consequences, for instance java, scala, go are all garbage collected which certainly comes with a performance penalty.

I doubt that those exact features were put to test - garbage collection has nothing to do with this paper - and I doubt that it had anything to do with memory allocation. As a side note, I found that garbage collection does work better than manual memory management in memory-intensive programs.
