Slow Remote Buffer Updates

Kenneth Jacker
[ Ubuntu-10.04.4;  Emacs-23.1.1 ]

I am running Ubuntu in my office and at home.

My usual "home mode" is to SSH (w/ X11 forwarding) into my office
machine (over a high speed cable connection) and start Emacs.  Once the
Emacs "frame" appears on my home display, I check for "todo items"
within Planner.

Say I find a "task" that has been completed.  I move "point" to the
corresponding line and enter "C-c C-x".  The task is eventually marked
as "done", but it sometimes takes up to 10 seconds to update the buffer!

My hunch is that it has something to do with "fonts" ...


Can anyone suggest change(s) to make my "at home" Planner performance
close to what I see when I'm using Emacs in my office?

Thanks for your help!

What happens if you run "emacs -nw" instead?

In that case you might try switching off font-lock mode, e.g. in your .emacs:

(global-font-lock-mode 0)

This might give a clue if your problem is related to X, or indeed more  
specifically to X fonts.

Markus

OK, will try that when I return home this evening ...

Yes, sounds like a good approach to isolate/identify the cause(s) ...


I do appreciate your (and others') help!
