[Zope] Timing SQL queries

[Andrew M. Kuchling]

Is there any support for timing SQL queries made by SQLMethods?  For
optimizing a site, it's nice to turn on a logging mode, exercise the
site a bit, and then look at a log of every query and the time it
took; this lets you notice redundant queries (means you need some
caching) or unusually slow queries (means you need an index or a table
rethink).  Any suggestions on how I should implement this, if it's not
already supported?
