On my 2017 15" MacBook Pro I saw 0.34 being faster than 0.33 (though nowhere near as dramatically as the improvement I saw on Fedora). On my 2013 13" MacBook Pro I see numbers much closer to those from my 2018 12" MacBook (non-Pro) which I shared earlier. Unlike the first laptop, the 2013 13" has active cooling and so is not thermally throttled in "normal" operation, yet I get 11500msg/s on 0.33 and 8800msg/s on 0.34 ... so I think the best we can say is that results on OS X are hardware dependant (all the laptops are running OS X 10.13). > Massive performance degradation in 0.34.0 > - > > Key: QPIDJMS-402 > URL: https://issues.apache.org/jira/browse/QPIDJMS-402 > Project: Qpid JMS > Issue Type: Bug > Components: qpid-jms-client >Affects Versions: 0.34.0 > Environment: Windows 7x64 + Oracle JDK 8u161x64 > Windows 7x64 + Open JDK 8u171x64 > CloudFoundry (Ubuntu Trusty) + Open JDK 8u172x64 >Reporter: Johan Stenberg >Priority: Critical > Attachments: QpidJms402_PerfTest.java, > image-2018-07-13-16-39-19-707.png, qpidjms402.zip > > > This is a followup issue for > [http://qpid.2158936.n2.nabble.com/qpid-jms-Severe-performance-issue-after-upgrading-from-0-33-0-to-0-34-0-td7678052.html] > I am attaching a simple test case that shows the issue.

Some previous testing on Macs didn't show similar slowdown, though it was under Linux. I wonder if that might be thermal related on the laptop in question, but Rob is going to try another system to see how it behaves. Your last comment is somehow in line with our thinking so far, that its getting in there and parking more than it does when not on Linux. [~tabish121] has one though on that I'm going to give a try out shortly. > Massive performance degradation in 0.34.0 > - > > Key: QPIDJMS-402 > URL: https://issues.apache.org/jira/browse/QPIDJMS-402 > Project: Qpid JMS > Issue Type: Bug > Components: qpid-jms-client >Affects Versions: 0.34.0 > Environment: Windows 7x64 + Oracle JDK 8u161x64 > Windows 7x64 + Open JDK 8u171x64 > CloudFoundry (Ubuntu Trusty) + Open JDK 8u172x64 >Reporter: Johan Stenberg >Priority: Critical > Attachments: QpidJms402_PerfTest.java, > image-2018-07-13-16-39-19-707.png, qpidjms402.zip > > > This is a followup issue for > [http://qpid.2158936.n2.nabble.com/qpid-jms-Severe-performance-issue-after-upgrading-from-0-33-0-to-0-34-0-td7678052.html] > I am attaching a simple test case that shows the issue.

Johan Stenberg commented on QPIDJMS-402:
It looks like the new implementation tries to be too clever. The by far best
results I by stripping down the sync method to this:
{code:java}
public void sync() throws IOException {
try {
int idleCount = 0;
while (true) {
if (isComplete()) {
failOnError();
return;
}
if (idleCount < SPIN_COUNT) {
idleCount++;
} else if (idleCount < YIELD_COUNT) {
Thread.yield();
idleCount++;
} else {
synchronized (this) {
if (isComplete()) {
failOnError();
return;
}
waiting++;
try {
wait();
} finally {
waiting--;
}
}
}
}
} catch (final InterruptedException e) {
Thread.interrupted();
throw IOExceptionSupport.create(e);
}
}
{code}
If idleCount is > YIELD_COUNT it seems much more efficient to directly go into
wait instead of doing the parkNanos magic first. Also I strongly believe the
"if currentThread.isInterrupted()" check is unnecessary. Removing it gives me
another good 8-10% higher throughput.
With this code change I get 45.000 msg/s with v0.34 compared to 32.958 msg/s
with v0.33.0. Without that code change I get between 100 and 1000 msg/s with
0.34.0.

Johan Stenberg commented on QPIDJMS-402:
Creating a new producer in each iteration was not on purpose but a mistake. I
changed the code and removed the semaphores. Running the test case I now get
these results:
v0.33.0:
Sent: 33844 msg/s Received: 35829 msg/s
Sent: 34337 msg/s Received: 35908 msg/s
Sent: 33868 msg/s Received: 32684 msg/s
Sent: 33907 msg/s Received: 35201 msg/s
v0.34.0:
Sent: 1097 msg/s Received: 973 msg/s
Sent: 1905 msg/s Received: 1582 msg/s
Sent: 3066 msg/s Received: 1638 msg/s
Sent: 2663 msg/s Received: 1666 msg/s
Still the new version is 10-30 times slower.
I now used openjdk 1.8.0u171 64bit on Windows 7 64bit (8core,16GB RAM).
I attached a maven project to reproduce the issue. You can now switch qpid jms
version via the qpid-jms.version system property:
{noformat}
mvn test -Dqpid-jms.version=0.33.0
mvn test -Dqpid-jms.version=0.34.0
{noformat}

[jira] [Commented] (QPIDJMS-402) Massive performance degradation in 0.34.0
[ https://issues.apache.org/jira/browse/QPIDJMS-402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16542876#comment-16542876 ] Robbie Gemmell commented on QPIDJMS-402: It would be more helpful if you gave a fully runnable reproducer (whether. a patch into the build or an entirely separate thing) and not just some code in isolation. That way know we are definitely doing the same thing in the same way, and folks can spend time looking into the issue rather than time figuring out what to do to get it running. I didn't see the same when I eventually ran your reproducer. 0.34.0 was significantly faster than 0.33.0 in my runs. On my ageing laptop I saw around 3000/s for 0.33.0, whereas for 0.34.0 I saw around 5000/s. Both our numbers seemed surprisingly low, so I then had a closer look at the reproducer code. A new MessageProducer is created and closed for every message sent, capping performance from the outset since that adds two synchronous operations per message. The async send inbetween them avoids adding another, though. The Semaphore stuff seems essentially dead code given how it is[n't] used, though it wouldn't normally have any effect if it were in play given the send process is still governed by message credit which is rarely going to allow that large a window to actually form. Changing the reproducer to re-use its sender, I got around 48,000/s with 0.33.0 and then around 71,000/s with 0.34.0 on my laptop.
