I've dug through the source, and to answer my own question: The 10x slowdown occurred only in the first iteration through the set. It turns out the PersistentHashSet (and others) calls RT which caused the clojure runtime to load costing about two seconds. Once the runtime is loaded it is 1-4 time java.util.HashSet for iteration which is fine. It would be nice to have a version of the clojure data structures which doesn't depend on the runtime. I may start extracting such a version myself. /Karl -- You received this message because you are subscribed to the Google Groups "Clojure" group.
