Re: Threadring Benchmark
So I got a chance to do some tweaks to the clojure code and run the benchmark. I also used the approved (not alternative) version of java code for comparison. I must say I am impressed with the clojure agent performance. The previous implementation results for 20,000,000 hops was: java: 27.14 sec, 92% cpu scala: 190.78 sec, 183% cpu clojure: 215.26 sec, 134% cpu The new results are: java: 33.56 sec, 94% cpu scala: 191.08 sec, 177% cpu clojure: 77.01 sec, 91% cpu The tweaks to clojure code were minor. Basically, coercing hops to (int hops) and using (neg? hops) instead of =.
