Yep, I did some very basic benchmarks (ab, ZopeProfiler, PTProfiler).
For the front-page for an anonymous user the rough numbers were:

Plone 2.5 trunk -> 5 requests/sec
Plone 3.0 some days ago -> 3.5 requests/sec
Plone 3.0 right now -> 4.0 requests/sec

Plone 3.0 without old-style portlets -> 6.0 requests/sec

And as a reference:

Zope 2.10 front-page -> 180 requests/sec ;)

So right now one easy way of getting some more performance is to turn
the remaining old-style portlets into new-style ones.

The plone.app.globals approach should allow us to optimize the
performance in some more places, so I think we are starting to see the
blessings of using Zope3 on the performance side as well ;)
