Binay payload uses lots of resource ?

[Nicolas Casaux]

Hello,

I’m facing an issue with the following setup. I have 100s of client from JMeter, all of them are connected via Stomp over Websocket to an Middleware. (ActiveMQ or ActiveMQ Artemis)

• Case 1:

  • all my clients are connected to ActiveMQ (via Stomp over Websocket) and subscribed to the same topic.
  • I send 10 messages to the topic of 20Kb payload size
  • Each client gets its message which is seen as Text message because of how ActiveMQ handles websocket
  • Everything is fine, not much CPU or heap usage by JMeter

• Case 2:

  • all my clients are connected to ActiveMQ Artemis (via Stomp over Websocket) and subscribed to the same topic.
  • I send 10 messages to the topic of 20Kb payload size
  • Each client gets its message which is seen as Binary message because of how ActiveMQ Artemis handles websocket
  • The CPU and heap usage of JMeter is huge, like 5 sec of 100% CPU, it almost freezes, sometime I get an out of memory error

My question is the following: does the plugin handles differently binary message and text message ? It seems that handling binary (and not that big) messages uses lots of resource compared to text message.

Thanks in advance for your response!

Nicolas

Hi Nicolas,

Not that i was aware of . I think i found the cause (creating debug log messages even when debug logging is not enabled). The fix is trivial, but i need a little time for testing and creating a release.

Thanks for your feedback.

fix: do not build large debug message when debug logging is disabled. This fixes issue 119 https://bitbucket.org/pjtr/jmeter-websocket-samplers/issues/67/change-request-accept-string-jmeter
