Dear Emacs maintainers:

Here are the steps to see Emacs editing this .html file very slowly.

1. Copy the file http://gnuplot.sourceforge.net/demo_canvas_5.2/simple.html

to your computer and open it in Emacs.

2. Press the down arrow key repeatedly.

3. Around row 55 Emacs will become very slow in its response.

This .html file has JavaScript. This may or may not be significant.

Yours truly,

Scott Haines
