Read time out with Single Read Sampler when JMeter send over 100 connections

[Former user]

Hi Peter Dorrnbosch,

Very thanks for the Plugins. My ThreadGroup: 1. WebSocket Open Connection, 2. WebSocket Ping/Pong 3. WebSocket Request-response Sampler 1 4. WebSocket Request-response Sampler 2 5. WebSocket Request-response Sampler 3 6. WebSocket Single Read Sampler 1 7. Websocket Single Read Sampler 2 8. View Results Tree

Number of Threads(users): 100, then I run this script. It says error: {quote} Response code: Websocket I/O error Response message: WebSocket I/O error: Read timed out

I just do the performance test for my product, but I don't know why some JMeter Websocket Single Read Sampler report Read timed out? over 100 connections If I set Number of Threads(users):80, then run this script, the Single Read Sampler show a pass test result.

thanks, ZBa

Hi ZBa,

Apparently, something in your test chain cannot handle that many connections that fast. I don’t know your environment of course, neither the value of your read timeout, but on a normal modern PC, 100 threads should be no problem for JMeter / the plugin. But you might want to check JMeter’s memory usage.

You are not accidentally using binary frames, are you?

Regards

Peter
