I noticed another thing with updates. Sometimes when I enabled the live check it loads a while but displays the same page with same equipment and cached date instead of live data. I have to load it again 1 or 2 times sometimes to get the new data. But when I tried this the armory seemd to work good and fast. Maybe the updating of the page does not work sometimes properly because of browser cache or other issues?
I use Safari 3 on a Mac.
