Description

At the school in Cameroon I saw that some Microsoft Windows computers were terribly slow (e.g. 30s delay after each line of input) when using CoCoA-5 inside emacs.

I searched on internet and found some descriptions of similar problems. The suggestion is to add the following line to dot-emacs

; try to improve slow performance on windows.
(setq w32-get-true-file-attributes nil)

This solution appeared to work on the machine I tried in Cameroon.

I suggest we add this line to our Emacs code (though this might interfere with an emacs expert's own dot-emacs?)

Of course, we cannot really test this...

I have been using CoCoA-5 inside emacs for over a month with the new line added to cocoa5.emacs, and have not noticed any (new) problems with the Emacs interface.

I cannot test it on Microsoft Windows, but simply hope that it does the job.
Closing.
