Do you mean a form that autenticates the user?  Zope uses HTTP basic
authentication, which is what pops up the dialog box.  Any other method
you want to use (cookies, form variables being passed around) you'd have
to roll your own.  Note that UserDB does cookie auth as well as basic.

As for the mysql issue, I suspect the bottleneck is purely a MySQL thing
if Zope doesn't behave that way all the time.  Note that even though you
may be running Zope in threaded mode, the MySQL client library for
python (which we did not write and do not support) is not thread safe,
so you should NOT run Zope 2.0 with more than one thread if you want to
use MySQL.  Someone may want to patch the MySQLDA so that the whole
thing is wrapped in a lock, or serializes requests before the client
library is entered.  Either way, given that no one is paying us to do
it, we probably won't.
