Google Name Java "Simplest to Implement"

Google have published a research paper that compares the performance of Java, Scala, C++ and Google's own Go programming language. Google implemented a specified compact algorithm in the four languages and evaluated the results along "several dimensions."Google concluded that Java is "probably the simplest to implement, but the hardest to analyze for performance," particularly regarding garbage collection, and found the same issues with Scala. Google also decided that C++ wins out by "a large margin" when it comes to performance, however, the report also stated that this language requires the most extensive tuning efforts, many of which are at a level of sophistication that is not available to the "average" developer. The full report can be viewed now (PDF.)
