   You are probably missing the fact that Emacs tries to optimize the

Perhaps it would be ok to delete this optimization,
or add a variable to control it and turn on the variable
only on the slower computers.

Given modern branch prediction and instruction caches, I wouldn't be surprised if removing the special cases in keyboard.c for self-insert- command, forward-char, backward-char were itself an optimization.

It'd also have the nice effect of making these commands behave normally for advice, redefinition, debugging, and so on.
