Well, hm, I have FLLargeIdentityDicitonary instances with up to 300'000 items... But that's what "large" means, right? Is there anything I can do here?

Thanks for this hint! I did that, and measured the same crazy difference, 6minutes vs. 1.5 minutes. So: It's not the storage! It's something inside Fuel. I keep investigating and will update here.
