RE: [NavigationTiming] Move window.performance to navigator.performance

Hi Folks,

In the meeting on 12/1/2010 [minutes<http://www.w3.org/2010/12/01-webperf-minutes.html>], as a working group we decided to go with window.performance as the official namespace for the Web Performance Working Group. We reviewed the risks of this name and its alignment to the working group's charter.

The decision was based on a number of different factors:

i.                     The namespace performance is much more suitable given the direction we want to take with this working group in terms of helping site operators and site developers access and understand their performance in user agents. Particularly as we move forward with adding functionality to this interface. The alternate names we considered were pagePerformance and webPerformance.

ii.                   The risks as outlined in Zhiheng's response and in our previous study on high traffic sites were found to be low for the name "performance".

iii.                  When analyzing the occurrences of pagePerformance, the analysis came back inconclusive, no concrete instances of "var pagePerformance" or "var webPerformance" were found.

Best Regards,
Anderson Quach
IE Program Manager

  So "pagePerformance" sounds good to everyone?

  Nic and Anderson found that 0.00993% of high traffic websites has performance object in
their scripts. It might not cover all the cases, but I sort of subscribe to the idea that these
developers should know about this draft, especially if they care about "performance". };->
That said, using a rarer name helps.


cheers,
