Mule ESB and maximum flow threads

Question

I went to the following site:

http://www.mulesoft.org/documentation/display/current/Tuning+Performance

and it says to alter the following 2 values:

maxThreadsActive and maxBufferSize

with maxThreadsActive being the number of active threads at anyone time, and maxBufferSize being the number of requests that can wait in a queue

But I am having difficulty finding any examples of how to do this in code.

-- Is there a central Mule ESB file where I can change the default number of maxThreadsActive and maxBufferSize ???

Would this be the dispatcher threading profile. What file would that be ?

--

If there is no central filet, for a synchronous process, how would I change the following code to use a maximum number of active threads to 100 and a maximum number of requests on the queue to 60

You can used a queued-asynchronous processing strategy in you flow. With this approach you can change the number of threads available to the flow.

For Example:

<queued-thread-per-processor-processing-strategy name="ProcessingStrategy" maxThreads="60" minThreads="10" threadTTL="5000" poolExhaustedAction="WAIT" threadWaitTimeout="5000" maxBufferSize="100"/>

<flow name="test1Flow1" doc:name="test1Flow1" processingStrategy="ProcessingStrategy">
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP" contentType="application/json" keepAlive="true"  mimeType="application/json"/>
    <echo-component doc:name="Echo"/>
</flow>

"You can specify a separate threading profile for each receiver thread pool, flow thread pool, and dispatcher thread pool". For example:

<http:connector name="DefaultHTTPConnector" clientSoTimeout="120000"  keepSendSocketOpen="false" >
    <receiver-threading-profile maxThreadsActive="500"/>
    <dispatcher-threading-profile maxThreadsActive="500"/>
</http:connector>

or

<configuration>
    <default-receiver-threading-profile maxThreadsActive="130" />
</configuration>

I recommend the first option in the flow. I hope to help;

Mule ESB and maximum flow threads

Would this be the dispatcher threading profile. What file would that be ?
