Did you read the article? The majority of the Clojure startup time is spent on initializing the Clojure runtime. "spends 95% of the startup-time loading the clojure.core namespace (the clojure.lang.RT class in particular) and filling out all the metadata/docstrings etc for the methods. This process stresses the GC quite a bit, some 130k objects are allocated and 90k free-d during multiple invokes of the GC (3-6 times), the building up of meta data is one big source of this massive object churn."

> The majority of the Clojure startup time is spent on initializing the Clojure runtime. That's correct but even without this startup time Clojure is significantly slower than other functional languages. Look at SBCL and Racket in http://shootout.alioth.debian.org/u32/which-programming-languages-are-fastest.php http://shootout.alioth.debian.org/u32/which-programming-lang... That doesn't mean that I don't like Clojure. I am even considering it for a business project. But Clojure is definitely unsuitable for small apps (shell scripts etc.) Btw the benchmark listing doesn't take LuaJIT into account. This JIT is the fastest I have ever encountered, way ahead of JVM regarding startup time.
