Bad performances

Key: SYNAPSE-287
URL: https://issues.apache.org/jira/browse/SYNAPSE-287
Project: Synapse
Issue Type: Bug
Components: Transports
Affects Versions: 1.1.1
Environment: Windows XP SP2, JDK SUN 1.5.0_15
Ubuntu Server 6.10, JDK SUN 1.5.0_15
Reporter: Nicolas KOHUT
Priority: Critical
Synapse has some networks problems.
When it is stressed, is freeze synapse in transport http.
This behavior is obtained by influencing 2 parameters:
- the number of competitors access (number of thread).
- the size of messages sent.
More generally, the higher the speed is high (combination of 2 parameters
above) synapse freezes more quickly.
A simple test case (using JMeter):
- Install distribution synapse-1.1.1 default.
- Setting up a proxy with sequences in and out empty.
- Launch a thread (1 single thread is sufficient ...) which calls the proxy
with a message 6Ko infinite loop. The thread sits 100 ms between each call.
Synapse must freeze (random) after about 2 000 calls (5 max 000).
The freeze takes place at a rate of 7 messages (6Ko) per second ...
The only configuration synapse that I could find is the file in the folder
synapse.properties Conf of synapse.
This file can affect a pool of thread used by synapse. Increase the various
parameters of the pool has no impact and does not correct the problem.
Listed JVM, jconsole indicates that there is no leakage and no memory thread in
deadlock.
Finally, the synapse approved http requests with nio-http (I do not know more).
Conclusion:
The simple test presented above is surprising. Synapse seems not to hold a
charge very light.
