118364 - Favicons performance issue

Status: RESOLVED DUPLICATE of bug 62907

(SeaMonkey :: Bookmarks & History, defect)

Description

[Dagan McGregor]

Running Mozilla 0.9.7 Mozilla/5.0 (Windows; U; Win98; en-US; rv:0.9.7)
Gecko/20011221

 Windows 98SE, with IE6 loaded (if it makes any difference). Mozilla set for
memory cache of 10240KB, in case you believe it is memory load related(I have
384MB RAM).

 When loading a bookmark file with a number of favicons in it, the menus will
slow down for the favicons to load fully.
 
 This can cause a pause of a second of two, depending on how many favicons are
loading, in the bookmark menus before they appear properly.

 Possible causes: 

 1) Favicons not loaded into memory cache when bookmarks are loaded (pre load).

 2) Favicons are not kept loaded into memory after they are loaded the first
time (bookmarks reload favicons each time the menus are loaded).

 3) Image display code is not optimised enough to load many icons at once (wild
guess).

 Preferred solution: Favicons should preferably be loaded into memory when
bookmarks are loaded in the UI at startup. This should save the initial pause
loading the images when accessing the menus.

 I guess the current state is set down so any changes in favicons will be
displayed immediately, without having to close the browser window (?). If that
is the case, then simply speeding the load of favicons each time would be
preferred over only loading them when the browser window is created.

 Either way, favicons should not pause loading of bookmark menus.
