Sadly, I think this is normal. Clojure on the JVM starts up in about 4-5 sec on my machine. I've found that Clojure-CLR is much slower. As an example here's what's happening: 1) the Clojure-CLR assembly loads 2) Clojure-CLR is run through some initial JIT compilation 3) Clojure-CLR loads core.clj which is about 200KB of Clojure code 4) core.clj is translated to CLR classes, functions, etc. 5) core.clj is run through the JIT 6) other supporting .clj files are read, translated, and run through the JIT 7) now you are at the REPL I think the only real way to improve these startup times is to do what Python does, and have cached assemblies so that core.clj doesn't have to be re-compiled each and every time. But as far as I know no one is even looking into this. Timothy -- You received this message because you are subscribed to the Google Groups "Clojure" group.
