Using Java MQ class, Client connection, Server 7.0 version.
It takes 20mins to send 10K messages to MQ. Similar C++ code takes 3secs. Below is the code:
MQEnvironment.hostname = "some ip";
MQEnvironment.channel = "some channel";
MQEnvironment.port = 1417;
MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES);
qMgr = new MQQueueManager(qManager);
int openOptions = MQC.MQOO_OUTPUT | MQC.MQOO_FAIL_IF_QUIESCING;
MQQueue mqQueue = qMgr.accessQueue("some queue", openOptions);
// the size of our message is around 700chars
String msg = "1234567890123456789012345678901234567890123456789012345678
9012345678901234567890123456789012345678901234567890123456789

90123456789012345678901234567890";
MQMessage mqMessage = new MQMessage();
mqMessage.format = MQC.MQFMT_STRING;
MQPutMessageOptions pmo = new MQPutMessageOptions();
int i = 0;
long tm_ms_start;
long tm_ms_end;
tm_ms_start = System.currentTimeMillis();
while (i <= 10000) {
mqMessage.clearMessage();
mqMessage.writeString(msg);
mqQueue.put(mqMessage,pmo);
i = i+1;
}
tm_ms_end = (System.currentTimeMillis() - tm_ms_start);
System.out.println("writeToMQ =" + tm_ms_end);
mqQueue.close();
qMgr.disconnect();
The output for this is
writeToMQ =1190172 (19mins and 53seconds)
Am I doing something wrong here? |

If the C++ code is taking 3 seconds for a 10K message there's something wrong! I would theorise it's using the same wrong construction as here, connecting & disconnecting after each put, which could easily soak up 3 seconds. Any WMQ application should connect once, get or put as many times as it needs, then disconnect.
I'll leave better minds than mine to comment on the specifics of your Java code.

Apparenlty it's not just English you have difficulty reading?
Granted, the code should have been in [ c o d e ] tags.
The only thing I see fundamentally wrong with the code is the transport. That doesn't look like the right value. |

I've been saying you need more Java for a while now.
