Google has published a paper (PDF) comparing performance of four programming languages, C++, its own language Go, Java and Scala. A team at Google created a "simple and compact" benchmark that didn't take advantage of language-specific features. An algorithm was implemented using each language's "idiomatic container classes, looping constructs, and memory/object allocation schemes."

However, the paper notes: "While the benchmark itself is simple and compact, it employs many language features, in particular, higher-level data structures (lists, maps, lists and arrays of sets and lists), a few algorithms (union/find, dfs/deep recursion, and loop recognition based on Tarjan), iterations over collection types, some object oriented features, and interesting memory allocation patterns."
