I think he means loading the program. Also, Azureus uses a nice chunk of ram. 100MB on my system, not a big deal to me, but might be to some. If you are using the safepeer plugin, theres an option you can tick to load concurrently or something like that. The plugin will load after you start the program so you don't have to wait.
I love azureus. It's very stable, I've never had it crash. And there are so many options you can configure for almost any kind of networking setup. It definatly gets my vote.
Just be sure to forward your ports if neccassary.
