I understand, but I mean this additional time when indicator in lower left corner has yellow colour (when browser loads data from scripts and plugins, right after red colour indicator) and when actually webiste looks as it is already rendered, in wiki there is advice to "enable ignore settings" if this takes too long, but I dont's see any difference when ignoring Ajax/Flash/GET or POST requests/FRAME (there is still same amount of additional time after loading page). For me it is extremely important to avoid any delays in project, I can't use GET/POST actions so everything need to be done in browser.
So it is posible to somehow shorten this addtional time to be less than 1 second (the best if it would be zero sec.).
