does anyone know of a good profiling tool or library for Clojure?
I would prefer something that could be used from the REPL, along the lines of (with-profiling ...) in Allegro Common Lisp back in the day.
Is there anything along those lines?
Or do you have any experience with (non-commercial) Java profilers that work well with Clojure?
I found VisualVM (see here and here) to be very convenient. Its use with Clojure has been described about a year ago in this blog post; as far as I can see, it’s not outdated in any way.
Note that the GUI from which one starts the VisualVM profiler has a prominent text area where one can enter classes / packages to be excluded from profiling — I find the results rather more useful when
clojure.*is on that list.
