Hope this question is not off topic..
I have successfully written my program after solving the problem I
posted here. It achieves the result, but the performance is a bit
slow.
I need to enhance the performance..
Here is a brief outline of my work till now, shown as a pseudo code:
//infinite loop
for(;;) {
String rsp = //get XML from remote URL ;
//remove DTD reference
rsp = rsp.substring(rsp.indexOf("<MESSAGING>"));
//parse response XML (using DOM API)
Document document = builder.parse(new InputSource(new StringReader(rsp)));
NodeList nodeList = document.getElementsByTagName("XYZ"); //this is
a specific tag which I want to read. It occurs many time (between
100-500)
//iterating the nodeList
for(int i = 0; i < nodeList.getLength(); i++)
{
//extract something ;) from current node
//send a response to a remote URL // (1): this establishes
a HTTP connection
}
//cause delay of 15 seconds - this is the pooling interval
Thread.sleep(15*1000);
}
Thats my program basically..
If you observe, sending the response (marked 1) (after detecting the
instance of tag XYZ in the inner for loop) for n number of tags(
nodeList.getLength() ) happens sequentially. But the end users would
expect high response time (this is a real time application).
Can I improve processing by running parallel threads? If yes, should I
create 1 thread for 1 response. Or can I divide the nodeList into
equal parts (lets say nodeList.getLength() / 5) ). So that 1 thread
will handle 5 responses. i.e. groups of 5 nodes will be handled in
parallel. What trade off should I do..?
Any suggestions please?
best regards,
