Hello everyone.]
My name is Hideyuki.
I'm Japanese (& poor at English).
I've got a trouble when I'm trying to optimize performance.
I want to:
1. set accept queue size 30.
2. process request on 3 thread concurrently.
So, I wrote below
---conf/server.xml start---
<Connector className="org.apache.catalina.connector.http.HttpConnector"
port="8080" minProcessors="3" maxProcessors="3"
enableLookups="true"
acceptCount="30" debug="0" connectionTimeout="60000"/>
---conf/server.xml end---
I think it's OK...
But when I send 30 request at once by LoadRunner, 27 requests is failure.
3 request is OK.
Is this a BUG? or a spec?
The source code is below.
I think we need own accept queue. Or Processor thread should do accept form
serverSocket directly.
How do you think?
---HttpConnector start (1028)---
// Hand this socket off to an appropriate processor
HttpProcessor processor = createProcessor();
if (processor == null) {
try {
log(sm.getString("httpConnector.noProcessor"));
socket.close();
} catch (IOException e) {
;
}
continue;
}
---HttpConnector end (1038)---
---HttpConnector start (834)---
/**
* Create (or allocate) and return an available processor for use in
* processing a specific HTTP request, if possible. If the maximum
* allowed processors have already been created and are in use, return
* <code>null</code> instead.
*/
private HttpProcessor createProcessor() {
synchronized (processors) {
if (processors.size() > 0) {
// if (debug >= 2)
// log("createProcessor: Reusing existing processor");
return ((HttpProcessor) processors.pop());
}
if ((maxProcessors > 0) && (curProcessors < maxProcessors)) {
// if (debug >= 2)
// log("createProcessor: Creating new processor");
return (newProcessor());
} else {
if (maxProcessors < 0) {
// if (debug >= 2)
// log("createProcessor: Creating new processor");
return (newProcessor());
} else {
// if (debug >= 2)
// log("createProcessor: Cannot create new processor");
return (null);
}
}
}
}
---HttpConnector end (865)---
