^ read. The OP responds in the thread.

tldr, literally what I said:

> It also makes everything slower (arguable where that ends up, currently significantly slower) overall.

longer version:

If there was no reason for it to be slower, it would not be slower.

...but, implementing this stuff is hard.

Doing a zero cost implementation is really hard.

It is slower.

Where it ends up eventually is still a 'hm... we'll see'.

To be fair, they didn't lead the article here with:

> Right now there is a significant single-threaded performance cost. Somewhere from 30-50%.

They should have, because now people have a misguided idea of what this wip release is... and that's not ideal; because if you install it, you'll find its slow as balls; and that's not really the message they were trying to put out with this release. This release was about being technically correct.

...but, it is slow as balls right now, and I'm not making that shit up. Try it yourself.
