Why doesn't Ubuntu provide the compiled version of emacs .el files
The listed *.el files
- are too small, too short, and over too quickly to benefit from Emacs Lisp compilation. Read them.
- are only encountered once, at
emacsstartup.
A better usage pattern is to start emacs once, enable (server-start) in your ~/.emacs, and use emacsclientto access and reaccess it.
In your ~/.bashrc,
export VISUAL=emacsclient
export EDITOR="$VISUAL"
alias emacs="emacsclient"
will make using emacsclient easier. Read man emacsclient.
