Slow loading of large streams

[alexandre-sjc]

I'm using the lib, and I've set up a large flow and I've noticed that when loading it, it sometimes takes 5 minutes to render on the screen when loading nodes.

Please, I need some help, some direction because I've done everything and it's ready, but I can't put it into production.
