Bad numbers in getReadMessagesThroughput and getWrittenMessagesThroughput from
acceptor using DemuxingIoHandler
---------------------------------------------------------------------------------------------------------------
Key: DIRMINA-501
URL: https://issues.apache.org/jira/browse/DIRMINA-501
Project: MINA
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0-M1
Environment: AIX/Windows with JDK5/JDK6
Reporter: Frederic Bregier
Priority: Minor
I ran an simple example that do the following :
- One server is configured using DemuxingIoHandler and
ObjectSerializationCodecFactory
It will print every 100 messages from one particular client the statistics
available from the acceptor.
- One client generates 30 threads and each are configured using
ObjectSerializationCodecFactory.
Each thread will send 1000 simple messages and one particular thread will
print statistics available
from the connector.
Bytes (Read or Write) and Message Write seem OK.
But Message Read are always 0 on server and should not.
This is not critical bug but I did not find the reason until now. So I will
join my code example
in order to allow one to reproduce the problem.
Here are some example of output:
