SUMMARY

The discussion centers on the high processor usage caused by Yahoo Mail when accessed through Internet Explorer 9, as opposed to Google Chrome, which operates without similar issues. The user observed that Yahoo Mail significantly taxed the processor, particularly utilizing a second core, while Chrome returned to idle state when Yahoo was accessed. The conclusion drawn is that users should transition from Internet Explorer to Google Chrome for a more efficient experience with Yahoo Mail, as the former appears to have compatibility issues that lead to excessive resource consumption.

PREREQUISITES
  • Understanding of browser performance metrics
  • Familiarity with Internet Explorer 9 and Google Chrome
  • Basic knowledge of processor core utilization
  • Awareness of web application compatibility issues
NEXT STEPS
  • Investigate browser performance optimization techniques
  • Learn about web application compatibility across different browsers
  • Explore tools for monitoring CPU usage by web applications
  • Research the impact of Flash content on browser performance
USEFUL FOR

This discussion is beneficial for web developers, IT professionals, and users experiencing performance issues with Yahoo Mail in Internet Explorer, as well as anyone interested in browser compatibility and resource management.

So probably from experience and convenience I use IE (9 now) as main browser and secondary Chrome. This came from the time that Yahoo seemed not compatible with Chrome and gmail is still very uncompatible with IE for me. It doesn't work - but that's not the issue now.

I also found that it as Yahoo that tried to saturate the processor in IE as can be seen in these screenshot (only one window IE active and one window paint for collecting the screen shots).

Starting up Yahoo and putting in password, selecting mail:

Steady state yahoo mail on, idle, no actions (notice the second branch of the processor).

Terminating yahoo,

So then I tried yahoo in google chrome, where it had not worked properly before and the processor worked fine, going back to idle when nothing happened.

So that means that the simple solution is to forget about IE and switch 100% to chrome, but my question is what is Yahoo doing in IE with that second branch? Stealing processor time for unknown purposes?

Anybody any idea why yahoo in IE sends the second core into high activity. Nothing else does this.
 
Is yahoo flash based?
