I mean in the sense of high-performance applications. I'm sure it's fast enough for average. Since other commenter mentioned SIMD, I'm going straight to examples to see what the speed is like. Good test cases would include a key-value store, web server of at least lighttpd complexity, game like Quake (esp interested in fps), top Prolog vs imperative engines for parsing/NLP, MP3 player, and so on. Stuff that taxes even imperative programs for speed. I'd love to see Prolog do those with similar speed (esp no pauses on real-time). Either of you have examples of such things? EDIT: And what's the story on concurrency in terms of safety and scaling?
