It's worse than that. Try hitting your banner ad more than once at the same
time. You'll get requests failing due to Zope trying to update a single
object with overlapping transactions. If you run the server in debug mode,
you'll see the Z2 Conflict errors.

Warning: don't trust Zope's error messages if you suspect you're getting
conflicts. There's an open bug for Zope's apparently randomly chosen error
messages to the browser when conflicts occur. Should be fixed in 2.1.

Jim Fulton at Digicool might have some suggestions as to how to re-architect
the product so that it doesn't suffer from conflicts. All I can think of is
abandoning the ZODB for the hit counting functionality.

Regards,
Garth.
