I've submitted two bugs. The first time it took about 3 minutes to load the login page and about another minute to let me log in. Typed out the relevant text, hit send and it was off. Second bug submission took only a few seconds to load.
I liked that I didn't have to package up relevant log files - the app did that automatically. Consider this - the app could be aggregating/collecting log files, which could explain the length of time to load the first time - just a thought...
