Hi,
I compiled emacs 23.2.1 in my home dir on a linux cluster (amd 64 chips) at
work. I connect over VPN from home, where I have a cable modem. For a long
time, emacs 21.4 *run as an xwindows app* (not "emacs -nw" living in a
terminal) has performed fine - after it starts (which may take some time),
typing, switching buffers, etc is pretty instant. But, doing the same thing
in 23.2 gives much slower response. Both work fine in -nw mode, but there
are some reasons (keyboard mappings, multi-windows, mouse) why I like the
full xwin app. From my office, both xwin's run very fast.
Any ideas on why? I just do text, no image stuff in emacs. I'd really like
to use emacs 23, remotely, the full xwin app, and have the speed be like
emacs 21.
Thanks,
David Strozzi

At a guess, because Emacs 23 uses Xft for font rendering, which provides nice
anti-aliased display, while Emacs 21 uses only X core fonts.
Theoretically the X server caching and client libraries make Xft reasonably
efficient over long, thin pipes, but practically it is optimized on the
assumption that people basically don't do this any more.
If you can live without the better fonts you can still turn on the core font
backend after install[1] and just use that.
Regards,
Daniel

From the NEWS:
*** Which font backends to use can be specified by the X resource
"FontBackend". For instance, to use both X core fonts and Xft fonts:
Emacs.FontBackend: x,xft
If this resource is not set, Emacs tries to use all font backends
available on your graphic device.
*** New frame parameter `font-backend' specifies a list of
font-backends supported by the frame's graphic device. On X, they are
currently `x' and `xft'.

Sounds like a bug we'd like to know about. Please M-x report-emacs-bug.

I've already done a bug report based on the
"Why is Emacs so slow when used remotely?"
thread.
Was it received? Was it clear enough?
Unlike other projects, I don't remember getting email on bug
reports for emacs as they change status. Sort of leaves us
in the dark.

Yes, we recevied it, as you can see at http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7092.
I see, then it is probably somewhat specific to dired.

We're not very good at using the bug-tracker, indeed (it's the right
place to submit reports, tho).

I think the OP complained about buffer list too.
I use Electric buffer list, it has tool tips and is easy
to get backed up if you mouse around it.
The mode line and window separators detect hover too and
seem to cause problems.
I just tried again, and I'm still seeing backed up tool tip windows
popping up as I type this in a local copy of Emacs.

Thanks.
I know I can disable tooltip mode but I don't see how to disable
all the hover stuff going on. I think it's too much for remote
use.

See this thread and see if it applies to your case:
