Description

12 years ago
Ways to see slowness with http://del.icio.us/jesser or the testcase:

* Just load the page, and hover over toolbar buttons to see that Firefox is unresponsive for a second or two during the load.

* Make sure Firefox is set to not show the tab bar when there's only one tab.  Load the page in the only tab, then middle-click the Home button.  There is a delay of about a second before the new tab appears, and a similar delay if you close the tab.

* Resize the window while the page is visible.

bz says "most of the time is in reflow... 105586 nsBlockReflowState::AddFloat" (with the original page, not the testcase).

This is less painful now that del.icio.us lets me set a cookie to restrict which tags appear in the sidebar (the "use minimum" option at the bottom of tag lists).

WFM with the "fairly simple testcase", but http://del.icio.us/jesser is still bad :(
