Fair enough.  I shouldn't have said "lousy performance of the
framework itself" when I should have included the application.  If the
application's page computations are so lengthy, then they too need
speeding up.  

We've got a situation where some big sites (Slashdot, Wikipedia) have
a lot of cached static pages for non-logged-in users (they all see the
same thing), but any user who is logged in sees a version customized
by their preferences, that's usually not cached.  So there's a
perverse incentive to not log in, since you see the static page
faster.

I'd really like to get hold of a big active blog or BBS server to
profile it.  It's been puzzling me for years what makes them so slow.
They just paste user-contributed content together with HTML from
templates, so you'd think it shouldn't be too complicated.
