I am sure it has to do with the number of packages. I have watched the time to go up. I can remember when it used to take 5-6 minutes. Keep in mind that I have not really used v285, and I have barely used v284. I usually run a number of things at a time because I am a music junkie, so iTunes is always running in the background, and Firefox or Google Chrome is open because I am on the forums or working on websites all of the time. I can get a more official time when I get home. The 10 minutes things is a ballpark number, but it is somewhere around there. I do not mind. Most people have little to no reason to have over 700 packages in their Installers folder.
Edit: The combination of unreliable memory, the v284 update and me closing
most things makes the 1:35 stops my excitement from sending me out of this chair. I seriously used to go do something else while I let the Installers tab load. That is just awesome! I wonder if it still takes ~6 minutes to rebuild the Bashed Patch for a 300+ mod setup.
Edit: By the way, my list is currently 864 packages strong, but now that does not bother me at all. I care about the load time, not the package list length. The package list is sorted and labeled. ^____^
