Assuming mysqlUserFolder caches the authentication tokens (and it very
likely does), there should be only a minor performance drop when using an
RDBMS.  The ZODB has built-in caching that reduces the time it takes to
access authentication tokens to something on the order of nanoseconds :-)
while SQL authentication without caching can easily take up to 100 ms per
request, which would be noticeable.

You could analyze the HTTP log, Z2.log.  To query the members folder use a
Python script like:

return len(container.Members.objectIds())

For email properties look at what the "roster" method does.
