Perhaps this applied to Jaguar, but at least over the week since installing Panther I've noticed Safari (1.1) slowing down. Lot of spinning beach balls. Puzzling about it, I finally realized that it seemed to be pages that had FORMS for me to fill out - even simple form pages that I visited often (e.g., Amazon book search). Having recently discovered how many Apple apps seem to store data in (ever-growing) XML document, I wondered if a search of such XML docs explained the slow-down.
FORTUNATELY, Apple lets you turn off AutoFill Web forms for "Other forms" without turning it off for "User names and passwords"! After doing so... NO MORE BEACH BALLS! Hope that helps somebody else - I hadn't seen it discussed here.
UNFORTUNATELY, I *loved* how helpful the autofill process was - it's just got too high a performance hit for me. I guess the same explanation lies behind the increasing lag when I click on a BookMark Bar folder (in my admittedly huge list of bookmarks) - a second click on a folder in BookMark Bar yields instantaneous results (coming, I guess, from a cache).
YOUR COMMENTS?: What approach to reading/writing info from XML docs is Apple using that slows performance so? How much stands in the way of their enhancing this so that such handy features as autofill for "Other Forms" doesn't mean taking such a performance hit?
