Tuning Fuse ServiceMix

[stephane_stephane.pain]

Hello

  I trying to tuning Fuse ServiceMix. I have an application that call a HTTP Endpoint Consumer. This application is a mult-thread application which can call a lot of time Fuse.

I log the execution of each call to Fuse.

I already change the file org.apache.servicemix.jbi.cfg and the parameter corePoolSize :

corePoolSize=50

My problem is when I call Fuse with one thread, the execution time is T. But if I have 10 threads t1, t2, ..., t10 which call Fuse (the same endpoint), the exceution time is T1 < T2 < T3 < ... < T10 and T10 = 2 * T

So my question is why the execution time increase when I have more then 1 thread ? I'm agree, the execution time must be increase if I have maybe 100 threads or more, but with only 10 threads.

How can I tune Fuse for have a best execution time ?

Thank you for your help

Best regards

Stéphane

This configuration you refer to is for JBI. Are you sure you are using JBI?

You can read about JBI thread pools configuration at

http://fusesource.com/docs/esb/4.4.1/esb_runtime/ESBRuntimeThreadPools.html

And it really depends on what you are doing with the messages in terms of performance gains. If you do CPU intensive processing then concurrent threads will compete for the same resource (CPU) etc.

You would need to profile or something to have a better understanding what is going on.
