I'm not sure if the MSXML parser was designed with the client in mind or not
- I recall hearing somewhere that someone at Microsoft was annoyed that
MSXML was so closely tied to the browser, since it was <em>meant</em> for
the server.  (This recollection of mine is not necessarily accurate,
however, and even if it is it's only hearsay.)

But in the project I'm on now we use it on both client and server.  Most of
our inter-component communication is done via XML, and there's quite a bit,
so MSXML is doing a pretty good job there.  (Sorry, no numbers.)  There is
also a daily batch job that runs, where our server-side MSXML component is
processing a largish XML file (somewhere between 400 and 600K), and it's
having no troubles with that.

Not exactly concrete proof one way or the other, but for our needs MSXML is
doing well on the server, and I haven't seen any scaling problems yet.
Someone else might have better numbers for you, though.
