Launcher too slow

Did you try just running a Compact Storage from the Utils section of the Settings app?

2.3 seconds is not normal, and I imagine the delay is because your filesystem is fragmented. The plan is to add something to sort this out automatically very soon.

How could I "enable internal flash"? I'm not sure what that means. :D

It requires a custom build of the watch firmware. Probably not something you want to try just yet :)

and put it in a function that stops my timeouts and executes the launcher....

The issue here is you've got to try and stop everything - like touch/swipe/accelerometer/gesture/GPS/barometer/etc events - and many more. But yes, in your own personal branch you could actually overwrite Bangle.showLauncher with your own function that does that.

There's nothing specifically in load that makes it slow. Maybe don't do this yourself as you'll have to overwrite the bootloader, but:

>require("Storage").write(".boot0","print(getTime())")
>print(getTime());load()
512.08120727539
512.13412475585

So the actual process of loading something takes only 0.05 sec.

It's just what's in .boot0 (the bootloader) and your app that actually slows things down.
