1. Create a new brain.
  2. Add 1024 children to the main thought.
  3. Export the brain to a PB XML file.
  4. Close the brain.
  5. Create a new brain.
  6. Reimport the PB XML File into the new brain.
Somewhere between the thoughts 500 to 700 you system starts crawling. That's just an excercise to test how robust the brain is and how well it scales in an extreme situation.
I did a similar exercise with 4096 thoughts (16 thoughts with 256 children each) overnight. It was hopeless. The brain stopped the import somewhere between 1200 and 1300 thoughts.

What we need to know:
  • What are reasonable limits for the number of thoughts, children, parents and links in a 6.x brain?

Reinhard, TB, WIN 10

Quality is the result of attention paid to details.
It sounds like you may have found a problem with the import function in the beta. We will check into this.

4096 thoughts is really very few overall. There are many brains with over 100,000 thoughts in them.

If you link a couple thousand thoughts to a single thought (whether parent, child, or jump), there may be a slight delay when activating the thought, but otherwise no ill effects. I wouldn't recommend this - primarily because it is a poor way to organize. There is no hard limit to the number of relationships, however linking more than a thousand or so to a single thought is just not a good idea and will affect the responsiveness of the UI when activating that thought.
