Roger Kapsi updated DIRMINA-532:
--------------------------------
Attachment: MINA-116-vs-M2.tar.bz2
Some screenshots, take a look at the number of scheduled messages. MINA needs
quite a while to write them even though the number of bytes is not crazy for an
100MBit/s Network.
> Slow writing compared to MINA 1.1.x

> Key: DIRMINA-532
> URL: https://issues.apache.org/jira/browse/DIRMINA-532
> Project: MINA
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0-M2
> Environment: Linux with 2.6.16-xenU Kernel, Java 1.6.0_02-b05, 18
> small instances on Amazon EC2 (1 Server, 17 clients), 3600 TCP connections to
> the Server

> Hi,
> we have a system built on top of MINA. Let's say it's an application server
> built a bit like a P2P system. We're currently focusing on the server side to
> get the most out of it and the client side is experimental (we use something
> else in production which is not based on MINA). From time to time I'm testing
> the latest MINA builds to check if we can start using it. I don't know how
> previous builds of MINA 2 behaved as our client side of the code is
> relatively new but MINA 2 seems to be slower than MINA 1.1.x.
> It seems to have problems with writing the messages as soon as I put some
> load on the Server and the number of Threads from the ExecutorFilter shoots
> through the roof.
> Configuration for MINA 1.1.6 & M2
> ThreadModel: MANUAL
> Send Buffer Size: 256k
> Receive Buffer Size: 256k
> Backlog: 200
> ExecutorFilter's position is right after ProtocolCodecFilter in the
> IoFilterChain.
> I'm going to attach some JMX screenshots. Feel free to make suggestions
> regards the setup and I'll try to test 'em ASAP.
> Thanks
> Roger
