Hello again,

In my experience, large files with few line ends (like minified JavaScript
files) tend to lag more. Sometimes I just use vim for these kind of files
or, depending on what I want to do, grep or sed in order to avoid opening
it in Emacs. But that should be a rare case rather than the rule.

I like to think of Emacs as a code editor (mostly) which works great for
development, but not necessarily for debugging.

Byte compiling your major modes may speed up processing, but I don't think
of it as a general performance solution. This "tip" should apply only for
custom installs because the default/built-in ones are already compiled.

In case you can share the file that you have trouble with I will gladly try
it on my system.
