Not to me.

But it's not hard to write equivalent code to his examples in D and get your own times to compare to his. If you compile on similar hardware, you'll get a good idea.

I'd also expect his compile-time code execution engine to be in a better state that DMD's CTFE engine is currently (but Stefan is working on fixing that).

He's building a game with Jai that compile in under a second. Small examples aren't indicative of how fast a compiler can compile when projects start getting larger. D isn't fast even with smaller examples if you include the wrong standard library modules.

"New CTFE" has been a WIP for years. I did take a look at it a while back and I'm not surprised it's taking so long to implement. It might very well be a few more years before it gets completed, and I can see it being really unstable when it does eventually get to that point.
