[jira] Created: (QPID-301) Tune performance when reading message
content from client
Tune performance when reading message content from client
---------------------------------------------------------
Key: QPID-301
URL: https://issues.apache.org/jira/browse/QPID-301
Project: Qpid
Issue Type: Improvement
Components: Java Client
Affects Versions: M1
Reporter: Marnie McCormack
Fix For: M2
The following code:
public void onMessage(Message message)
{
sLog.info("message received");
if (message instanceof JMSBytesMessage)
{
String correlationId = "unknown";
try
{
JMSBytesMessage requestMessage = (JMSBytesMessage) message;
// Read and deserialise message
String requestMessageString = requestMessage.toBodyString();
correlationId = requestMessage.getJMSCorrelationID();
takes 5ms to execute on an opteron Linux server, with a 100K message. User expected sub ms performance from this test. Auto acknowledge mode.
Note that bytes message sent from C++ client publisher.

[jira] Resolved: (QPID-301) Tune performance when reading message
content from client
Posted by "Robert Greig (JIRA)" <qp...@incubator.apache.org>.

Robert Greig resolved QPID-301.
-------------------------------
Resolution: Invalid
Fix Version/s: (was: M3)
Turning a 100k bytes message into a string is not going to a particularly cheap operation.
No idea why the user thinks that should be a "sub ms" operation.
Closing as invalid since it's not really a qpid issue - we provide access to the raw bytes so if someone can do better than the Sun string converter (which is very likely if all their data is ASCII for example) they can go ahead.
