My site does about 5 millions hits a day and 1 million
of these are through CherryPy 3.
CherryPy is not a significant factor in the
performance of the site - it's all down to the
database. I started off using SQLObject but then just
started using my own queries which was a lot faster
but slightly less convenient. I also use memcached for
almost everything which has made a huge difference.
