Frans, thought you'd like.

Nice Scary graphs btw. Not sure they'd need all that. Instantiating an LLBLGen Pro entity class isn't that complex as those graphs (but still more complex than a poco class instantiation).

And indeed.. measure and then jump to conclusions. The graphs show that if you cut features you'll get better performance, but then you'll miss features. Same with us, really.
