This reminds me of another thread, where performance issues related to concurrent allocation were explored in depth: https://groups.google.com/d/topic/clojure/48W2eff3caU/discussion The main takeaway for me was, that Hotspot will slow down pretty dramatically, as soon as there are two threads allocating.
Could you try: a) how performance develops, when you take out the allocation (assoc) b) if increasing Hotspot's TLAB size will make any difference? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
