I have done the benchmarks and optimized the implementation. On my PC with the new changes TransactionalMap is up to 5 times slower than ConcurrentHashMap. You can find the benchmarks here:
https://github.com/CERN-BE/Entwined-STM/blob/master/src/test/java/cern/entwined/demo/clojure_benchmarks.clj Just require the namespace and run either (time (run-concurrent-map)) or (time (run-transactional-map)). Please note while ConcurrentHashMap is faster in this test it does not give same guarantees as the TransactionalMap. For example in the benchmarks I created 1 thread per key that is being incremented if there was more than 1 thread updating the same key than ConcurrentHashMap wouldn't be suitable any more. I will release the improved new version 1.0.1 later this week. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
