Hi Vladyslav, firstly, no reason to get desperate :-) Glad you did some profiling, it would be super helpful next time around if you share more details about both your code an profile you're observing. It's hard to give advice what can be improved when given a blank canvas (no idea what your code looks like).
Of course things can be improved, and in fact just a few days ago we merged a significant performance improvement that affects the Framing stages: https://github.com/akka/akka/pull/21539 Keep an eye out for 2.4.12. -- Konrad `ktoso` Malawski Akka <http://akka.io> @ Lightbend <http://lightbend.com> On 19 October 2016 at 16:11:32, [email protected] ( [email protected]) wrote: After some playing with JMC and async boundaries it turned out the hottest methods are related to ByteString splitting and delimiting (for example, scala.collection.IndexedSeqOptimized$class.sameElements(IndexedSeqOptimized, GenIterable) takes 73-75% of processor time). The input file is 45M lines, 2-3-characters each. Is it at all possible to make this work? -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
