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
Reporter: Roger Kapsi
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
