Mule ESB and maximum flow threads - mule

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

Answer 1

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;

Answer 2

You cannot add a flow processing strategy on a request-response exchange pattern

Answer 3

Add a global configuration element as follows:
