Yahoo Axis May Slow IE9 Browser Down
Installing new search add-on from Yahoo -- a Microsoft search partner -- may trigger Add-On Performance Advisor warning

Although Microsoft and Yahoo are search partners, Microsoft's Internet Explorer 9 (IE9) may complain that Yahoo's new Axis search add-on is slowing down the browser.

After installing the Axis search extension in IE9 on Windows 7 today, Computerworld found that the next time the browser launched, it popped up a message asking if the user wanted to disable Axis and other add-ons to speed up surfing.

The Axis add-on, which displays Yahoo's new search results motif at the bottom of IE, was at the top of the performance-affecting IE extensions installed on the test PC.

According to Microsoft, Yahoo Axis for IE slowed down IE9'S start-up by 0.07 seconds.

The add-on disabling message is not new or somehow triggered by Axis' installation: IE9 has had the feature, officially dubbed "Add-on Performance Advisor" -- since the browser launched in March 2011. The Advisor regularly shows warning messages when the combined slow-down time reaches a triggering level.
