Workarounds are using
- GRUB_CONSOLE=terminal
- or lowering the resolution
The problem here is that EFI GOP is framebuffer based console with no
video acceleration. At a high resolution it's very CPU intensive to draw
in that.
I suspect this could be somewhat by optimizing the GRUB code more.

I too am affected by slow console when GRUB_TERMINAL_MODE is set to
gfxmode in GRUB 2.04 and earlier versions. I believe this problem is
not resolution-specific; but suffers under VBE mode.
I can also verify that I don't have this issue with syslinux (which uses
VGA modes).

Lower resolutions make grub usable, but still slower than expected.

This bug is 11 years old and still present in the latest and greatest. A
fix should be easy - just force VGA resolution always as suggested by
Johannes. Fix please :)

The seperate /boot partition problem has been now fixed.
The version I uploaded yesterday shouldn't have any big bugs.
For me it works fine and I even uploaded this by accident to Debian unstable
