Timothy Bish commented on AMQ-5144:
-----------------------------------
Have you tried using a profiler to see where the time is being spent on the
stomp+nio+ssl case vs the others, perhaps that will shed some light on things.
> stomp+nio+ssl very slow message sending

> Project: ActiveMQ
> Issue Type: Bug
> Components: stomp
> Affects Versions: 5.9.0
> Environment: Linux 3.11.0-15-generic #23-Ubuntu SMP Mon Dec 9

> Hi there
> I have following broker config:
> <transportConnector name="stomp"
> uri="stomp+nio+ssl://0.0.0.0:61612?maximumConnections=10000&wireFormat.maxFrameSize=104857600"/>
> ACTIVEMQ_OPTS_MEMORY="-Xms1G -Xmx2G
> -Dorg.apache.activemq.UseDedicatedTaskRunner=false"
> And followind code snippet:
> {code}
> @Test
> public void plainStompTest() throws Exception {
> StompConnection sender = new StompConnection();
> StompConnection receiver = new StompConnection();
> System.setProperty("javax.net.ssl.keyStore",
> "/home/user/.keystore/client.ks");
> System.setProperty("javax.net.ssl.trustStore",
> "/home/user/.keystore/client.ts");
> System.setProperty("javax.net.ssl.keyStorePassword", "changeme");
> System.setProperty("javax.net.ssl.trustStorePassword", "changeme");
> SSLSocketFactory factory = (SSLSocketFactory)
> SSLSocketFactory.getDefault();
> SSLSocket sslsocket1 = (SSLSocket) factory.createSocket("localhost",
> 61612);
> SSLSocket sslsocket2 = (SSLSocket) factory.createSocket("localhost",
> 61612);
> sender.open(sslsocket1);
> receiver.open(sslsocket2);
> sender.connect("admin", "admin");
> receiver.connect("admin", "admin");
> receiver.subscribe("/queue/receiver");
> Thread.sleep(1000); // wait until subscribed
> char[] data = new char[toSendBytesMsgSize];
> Arrays.fill(data, 'a');
> long startTime = System.currentTimeMillis();
> logger.info("Sending message - size " + toSendBytesMsgSize / 1024 + "
> kb");
> sender.send("/queue/receiver", new String(data));
> StompFrame frame = receiver.receive(0);
> byte[] body = frame.getBody().getBytes();
> long stopTime = System.currentTimeMillis();
> long elapsedTime = stopTime - startTime;
> logger.info("Reply received");
> logger.info("Execution time = " + elapsedTime / 1000 + " seconds" + "[" +
> elapsedTime + " ms]");
> assertEquals(toSendBytesMsgSize, body.length);
> }
> {code}
> Results for stomp+ssl :
> {code}
> Sending message - size 1000 kb
> Reply received
> Execution time = 0 seconds[221 ms]
> {code}
> Results for stomp+nio : (i modified test client to not use ssl socket)
> {code}
> Sending message - size 1000 kb
> Reply received
> Execution time = 0 seconds[399 ms]
> {code}
> Results for stomp+nio+ssl :
> {code}
> Sending message - size 1000 kb
> Reply received
> Execution time = 54 seconds[54162 ms]
> {code}
> So from above we see that for stomp+nio+ssl it takes very long time to send a
> message.
> Anyone knows whats wrong ?
