Even if you load 50+ songs, I don't render all of the songs at once. I only render five pages ahead, so whatever songs happen to be in that range are loaded as needed. If there is an initial pause before anything shows up (including the first song), you could be encountering the delay from reading out all the database information for the songs before loading them. I find that pretty unlikely though, but you can test it. If you load the same setlist a second time, it should load much faster if the delay is due to the database as the data is cached and not loaded a second time. I'll have to try this out myself to see if there are any other bottlenecks with large setlists.
