Emacs Opening Large File Slow
While you have a large file, opening the file may be very slow.
The problem is almost always due to
font-lock-mode, which does the syntax coloring.
You can turn it off by Alt+x
then, open the file.
Another way to solve the opening large file problem is by using
find-file-literally. It'll open the file without syntax coloring, and without interpreting Unicode.
