Re: [Matlab-emacs-discuss] matlab-emacs slows down

Hi,

I used to have the same problem, and found it frustrating that there seemed
to be no discussion of this issue anywhere.  Finally, I was able to fix it
myself.

Here's what I did:

   1.  I ran matlab-shell with my usual workflow until it started becoming
   unresponsive.
   2. I started the emacs profiler: (profiler-start 'cpu)
   3. I hit enter a couple of times in the matlab-shell, waiting a few
   seconds for the shell to respond.
   4. I asked the profiler for a report (profiler-report)
   5. From the report, it turned out that most of the runtime was spent in
   a single function whose task is to render errors as anchors (which I don't
   particularly care about).
   6. This function is hooked into matlab-shell-mode when it start.  As a
   workaround, I added another hook that removes this hook, by including the
   following lines in my .emacs file:



*(add-hook 'matlab-shell-mode-hook       (lambda () (remove-hook
'comint-output-filter-functions
'matlab-shell-render-errors-as-anchor t)))*

 I have not had any issues with unresponsive matlab shell after I did
this.  If your problem has the same cause as mine, this hopefully works for
you too.  (Make sure to get the quotation marks in the above command right,
as well as the final 't' on the last line...).

Hi folks,

First, great job on the update to matlab-mode, a big improvement on
the version I was using before (~2003). One problem I've noticed is
that the CLI slows down considerably after a while, perhaps due to the
buffer getting large ( O(10k) lines). I usually end up restarting
matlab-shell to get the responsiveness back. Is there a better
workaround for this?

Thanks!

Sina
