I have not managed to hit a limit and I've had some monstrous trees. However, I've discovered that branching text trees horribly bog down the Foundry. I had several trees with at least 30 boxes, and the one with the most had 56. However, I had to remove them with the intention of putting them back in later because the Foundry became unusable. It took more than 30 seconds to place an item or adjust it, so I simply couldn't create any more maps.
Based on my experience you'll hit performance limits long before you hit hard limits. Granted, this could just be my machine. Maybe it's because I only have 2 GBs of memory, or a 2.5 GHz x2 processor. Regardless, I've learned to basically create my entire mission first and put all the dialogue in last. It's kind of a pain in the butt, but it's the only thing that will even remotely work for me.
