There a project to benchmark programming language performance: https://github.com/attractivechaos/plb2 • Might be interesting for someone to code up a Clojure implementation (if anyone feels like it!). I assume it should be able to perform just as well as Java (although it may not look very idiomatic e..g. using Arrays instead of vectors etc). • Java does very well in this table. • Python is still embarassingly far behind in this table.

I'm interested in how Java will perform if the code was run several times. Could even be better

these benchmarks seem to be focusing on very specific kinds of programming. i realize the goal is to compare the same algorithm across languages, but I don't know anyone who would write java like https://github.com/attractivechaos/plb2/blob/master/src/java/nqueen.java lol

Yeah it's certainly not idiomatic - but I think it's a reasonable style of Java code for writing very high performance methods.

Similar in style is the Computer Language Benchmarks Game, which for a few years included Clojure versions of its programs, but not any more. Very non-idiomatic programs in most of the languages represented, where people tweaked the implementation as much as possible to reduce compute time: https://benchmarksgame-team.pages.debian.net/benchmarksgame/

Some Clojure code that I wrote, and even better ones by Alex Miller, should still be in this old repo: https://github.com/jafingerhut/clojure-benchmarks

fun to see the old-style metadata in that code
