This is in the "DOM Attributes (jQuery)" section in dromaeo. Nearly 20% of the time is dealing with resolves (due to JM not PICing DOM stuff with getters?) and in particular calling XPC_WN_ModsAllowed_ProtoResolve is about 10% of the total time. Peter, is that used for just normal DOM objects too?
Depends on: 557358
Something to keep in mind is Dromaeo is using jQuery v1.2.3. http://docs.jquery.com/Release:jQuery_1.2.3 from February 2008.
Yes, but it's just using the DOM. A newer jquery may use the DOM slightly differently, but it may not.... Or do you have concrete evidence the attr() has been significantly changed since in a way that makes this bug somehow irrelevant to our DOM performance?
DOM performance is important regardless of JS lib or lib version so please keep digging/investigating for perf improvements. jQuery did do an overhaul of their attribute/property related methods in v1.6 http://blog.jquery.com/2011/05/03/jquery-16-released/
