Ticket #10720 (closed bug: worksforme)
Selector performance regression when parsing XML
|Reported by:||steveworkman||Owned by:||steveworkman|
Related to http://bugs.jquery.com/ticket/10377 jQuery 1.7 no longer supports selecting XML nodes by [nodeName='z:row']. The agreed workaround is to use "z
:row, row" as the selector instead.
Running this through larger amounts of data, I'm seeing significant slow-down in IE browsers when using 1.7 compared to using 1.6.4. JSPerf test can be seen here http://jsperf.com/node-vs-double-select
Performance appears to have reduced by half in IE8, Opera 12 and Safari 5.1 and by small amounts in other browsers. Chrome and Firefox performance is almost identical.
