Which, by the by, is a fairly common tradeoff in distributed
systems ... except that parsing data generally takes a lot LESS
than 10% of the application overhead.  I can't see XML changing
that equation a heck of a lot.

Also, in the big picture, execution speed is not the only important
factor in system development.  It's often important to have the system
done twice as fast (a number of studies have shown that Java programmers
are twice as productive as C/C++ ones), or be more stable when it's been
declared "feature complete" (e.g. no pointer smashes).

And Sun, too.  One should also keep in mind that C based systems have been
evolving for 20+ years at this point, vs a lot less for Java.
