profiling in clojure (for large code)

Question

Search on Google shows some results for clojure profiling. Profiling tool for Clojure?
This link shows that profiling will blow up if large code is there. http://richhickey.github.com/clojure-contrib/profile-api.html. Is there any stable profiling tool for clojure? I need to profile huge library made in clojure with some clojure functions of upto 400 lines.

We've used YourKit successfully. No special steps - just set it up like any other JVM app. Of course, interpreting the results is a bit of an art form. You can play with the filters to sometimes get it to ignore clojure core.

I found it useful to set it up on a swank server which let me profile parts of the app in the REPL (and turn things on and off between runs).

I have installed it. While profiling with Eclipse, its asking for applet. whats should be done? – vikbehal Dec 07 '11 at 10:36
Not sure what you mean. I haven't used it from Eclipse. You want to set up your Clojure app (or repl) using J2SE profiling - several options doc'ed here: http://yourkit.com/docs/10/help/profiling_j2se.jsp – Alex Miller Dec 07 '11 at 14:53

Which do you need to do - profile? or speed up the code? If the latter, check out random pausing.
