High CPU usage in Firefox browser (19.0.2) running WebSocket (1.0.11) in jetty 8 server

Hi

We are using GWT Atmosphere Websockets(1.0.11) on jetty 8 server.
In our application, Server would send the text send to client browsers using websockets. Application works fine in all browsers except in Firefox browser. Client running application in Firefox browser consumes high CPU while showing the text on the browser.

Any idea what could be the issue.

Earlier we had same issue in chrome also, but when we replaced old atmosphere jars (0.9.4) with new version 1.0.11, issue looks to be resolved.
Note : We are using GWT Atmosphere.

@harishalwala you need to gives me more information about what is causing that and how to reproduce the issue. A test case would be really appreciated.

Can you profile using Firebug the client side? That will gives you what is eating the CPU.

I will check and let you know

I have done the profiling using firebug in Firefox browser, it points to a method in third party js file. However since I am working with GWT application, I dont think there will be any help even if profiler shows issue in js file. Is there any other way to validate the issue.

Hard to say....try to reduce the script at minimum, remove Atmosphere and see if you can pinpoint the issue (more details). Closing this issue as not a bug (in Atmosphere)
