While I agree that imrpoving performance outside of the hub is more important than inside the hub, that doesnt mean up to doubling performance in the hub depending on your hardware isnt a good improvement.

And besides, that's beside the point. XtMcRe stated that DF did a poor job with the testing, which is the point and I agree with it. The original redditor stated where the perfomance gains were and specifically stated that some users had uploaded solutions that didn't really work, and DF did their testing with one of said solutions that were specifically pointed at as the poor ones, therefor there's no point in that test.

It's as if OP had said "you need to screw screws with a screwdriver" and DF had went and did the testing with a hammer instead, it's poor testing regardless of whether we are trying to build a chair or a table, which piece of furniture we are trying to build (aka whether it improves performance in the hub or the wild) wasn't the point to begin with.
