I am curious to know, if there is any explanation for why java performs better than Go.

20 years of optimizing tends to do this

Go was invented in the 1970s and then placed on the self for 40 years

  I personally enjoy Go but your comment gave me a chuckle since it's very true. Have your upvote, friend, for whatever they're worth on HN.

I can't speak to the Java comparison, but the site says they used Go 1.6.3. The SSA back end introduced in Go 1.7 (amd64) came with a nice performance boost. https://blog.golang.org/go1.7 https://blog.golang.org/go1.7

Two decades of optimization probably account for that. From the paper: Moreover, the top 5 languages that need less energy and time to execute the solutions are: C (57J, 2019ms), Rust (59J, 2103ms), C++ (77J, 3155ms), Ada (98J, 3740ms), and Java (114J, 3821ms); of these, only Java is not compiled. That is an admirable accomplishment. JRE 1.8 has the most efficient "managed" language runtime tested. The PHP result is interesting; they used 7.x which is roughly twice as efficient as older (5.x) versions; PHP 7 was primarily a (successful) effort to improve performance. If you extrapolate the PHP result to the old version (multiply by 2) it's nearly as bad as Perl and among the slowest/most costly. That certainly corroborates Facebook's several PHP re-implementations.

  The Java performance was the most interesting part of the results for me. I'm glad it got some attention. I have been developing the opinion for awhile that, as an industry, we've become far too avoidant of "pre-mature" optimization. It is astonishing to me how much slower a lot of this stuff is than Java. Granted, I also think considering Java to be "not compiled" is a slight misrepresentation since it does get compiled to Java bytecode.
