Hi Boris, Thanks for packing it in a reproducible sample. As Viktor points out the Java serializer is one of the prime suspect for bottlenecks in remote communication. Here you have found something that I think can be improved in Akka remoting.
I can see that major time is consumed in EndpointWriter stashing and unstashing messages. That happens when the transport can't write. Perhaps some internal buffer is full. Please create a ticket<http://doc.akka.io/docs/akka/current/project/issue-tracking.html>and we will look into if we can improve the efficiency of this buffering mechanism. What you should do is to implement flow control in the application layer to avoid producing faster than what can be consumed. and also, implement a good serializer for your messages. /Patrik On Mon, Mar 24, 2014 at 1:58 AM, √iktor Ҡlang <[email protected]>wrote: > Hello Boris, > > Then you are likely to benchmark the slowness of Java Serialization. > > To maximize performance, one needs to choose an appropriate serializer. > > > On Mon, Mar 24, 2014 at 1:51 AM, Boris Capitanu <[email protected]> wrote: > >> Hello Viktor, >> >> I am using whatever default serializer Akka comes with.
