Vuze Speed Manager
Vuze needs to tell us how to optimize. I love the autooptimize, however, I'm knowledgable in this area, and can still find ways to speed my downloads in and outside of Vuze itself.
Vuze should recommend things I can do to speed my downloads, such as disabling the Firewall, the best port to avoid ISP blocks and other conflicts, and possibly recommend the ideal "Vuze capacity". Currently, Vuze offers you a few settings to determine the "priority" of the download, or the RAM preference. I'd like to be able to allow Vuze to use more RAM, in a recommended amount, that should pay attention to other applications open at that time.

You can try to prioritize your bandwith by adding the "wealthiest countries blocklist" to the ip filter while seeding
