[split] Debug toolbar? <CI4 is under development?>

I'm a little confused

Your image doesn't show anything out of whack. At the bottom of the page it shows the rendered time as 0.001 seconds, which is 1 millisecond. The displayed time in the Toolbar is 1ms. Those two match so far. The times that are being shown in the Timeline, like the Bootstrap time, is 0.64 milliseconds, not 64 milliseconds like you stated at the end of your post. Less than 1 millisecond. So - all of those times on the page work together and make sense as far as I can tell.

If you're seeing a 100x difference between what the browser shows in the developer tools then what the Toolbar is showing, then we definitely have something to explore. But you're not showing that.
