TUX is a linux only thing ATM, so any integration of the two
would have to be some sort of add on to a vanila zope.

There are important reasons why the figures are so different. In
the case of TUX, the kernel server tries to do as little work as possible
to translate a request into data flying out the NIC. Zope, on the other h=
and,
at the very least checks to see if the requester has permisson to access =
that
object, and often looks after other things like acquisition, setting cach=
ing=20
headers and obviously executing content generating code.

The easiest way for Zope to take advantage of TUX would be to have a TUX =
based
caching reverse proxy sit in front of the Zope server. All of the images =
and=20
other static content window dressing for the site which will always be se=
rved=20
up to everybody can have cache TTLs set so they quickly end up in the pro=
xy,=20
which can serve them up as fast as they can go.

If you still want to crank more speed out of zope, the next thing to do w=
ould=20
be to profile the steps needed to serve up requests for static content wh=
ere=20
having a permission system matters, and look into optimizing that.
