This Thursday, make sure you attend the NYPHP meetup at The Delancey -
there will be the first NYC Joomla meet. I'm hoping to be there.

That's not entirely correct - Joomla is great at handling lots of
content and lots of categories, it is the admin interface that isn't
really suited for it (by default, that is).
Perhaps it is time to create a second Administrator Template that uses
a different method to display and browse long lists, as opposed to
monster dropdowns that kill your browser... :-)

There's quite a few things you can do to tune up a busy Joomla site,
and MySQL query caching is just the start. An even bigger performance
increase can be found with PHP accelerators like XCache, APC and
eAccelerator. And when you go to 1.5, it's almost required as
everything is heavy on objects, and therefore gets the biggest boost
out of a cache and accelerator.
With memcached available in the 1.5 series, you can now cluster your
Joomla sites across many systems without too much effort.
*spacemonkey smells another article coming
And one quick note on the query cache - that's no good on community
style sites, as the tables are changing too rapidly for MySQL's cache
to be very effective. It is wicked fast on more typical,
corporate-style sites though.
