No. That problem is Plone/CMF, and most of the problem is in the
"skins". It's a combination of how portal_skins work, and the fact
that Plones skins are not very optimized. CPS, who also uses
portal_skins, are faster than an empty Plone site, for example, but
still not as fast as a pure Zope-site can be.

Zope 3 and Five both promises to solve that by it's "View" paradigm,
but neither Plone nor CMF uses that fully yet, so if you use a lot of
standard products that probably will not help you. I'm not a speed
guru, but load balancing with ZEO would probably be the easiest way of
improving the performance in this case. That's my guess.
