Emacs/psgml/xxml crawling

[Peter Flynn]

I've been using Emacs to edit SGML and XML since Len wrote psgml. For
the last decade (almost) I've been using xxml-mode as well for the nice
indenting and colorization. It's been absolutely fine, on half a dozen
flavors of Un*x, Widnows, and MAC OSs.

I installed my standard .emacs and assorted .els on a new laptop with a
fresh install of Ubuntu Gutsy a few months ago, all fine. I just
installed the identical OS from the same CD on a DELL Dimension 4550
desktop, updated from the same repos, and added the identical .emacs and
..els.

When I opened an XML document it started to parse the DTD, element 1
(long pause) element 6 (longer pause) element 10 (etc). it took 15 min
to parse the standard DocBook 4.4, which the laptop (and every other
machine I use, about a dozen, assorted) whizzes through in 1-2 secs.

Obviously there's something different, but it's not the .emacs or the
..els, which I copied from my own archive; and it wasn't the CD, which
was the same one. I've check file sizes and there are no differences
which might have indicated corruption.

It could have been whatever packages got updated when the OS install
completed, but they'd have been fractionally different anyway because of
the different platform. I'm slightly unwilling to believe that this is
down at the OS level given that the 4550 is behaving normally for all
other apps -- only Emacs parsing a DTD is running at 1/100 normal speed,
everything else, including the rest of Emacs, and (apparently) the rest
of psgml, runs normally.

Has anyone ever encountered this before, or got suggestions as to where
to start looking?

Check your paths, to make sure the Emacs you're executing is the one you
think you're executing?

If you're getting different results, odds are you're not running the
same code.

This symptom usually shows up when the DTD if fetched from Internet,
instead of using a local copy. Have you set up an appropriate catalog on
your laptop?

I should have added this...yes, it's my standard catalog, on all
platforms, and the symptoms persist when the machine is disconnected, so
it's not affected by Internet retrieval.

Good point. I'll check.

I'm damn sure it's not the same code.
Problem is, which bit :-)
