Plone's rich interface and deep customization provide excellent features for modern web sites. However, without planning and tuning, Plone sites can generate every part of every page, every time, causing slowness. There are excellent built-in features for speeding Plone sites up tremendously, however, with little or no loss of freshness or customization. This tutorial covers techniques for deploying Plone for performance, optimizing your site with CacheFu, using Zope's cache-in-memory features, and tips and techniques for tying it all together. In this class, you'll learn the tips and tricks professionals use to make their sites 20x, 30x, and even 100x faster than standard out-of-the-box Plone. This session, presented to a packed audience at the 2006 Conference, has been updated for new material and techniques for Plone 3, while still containing useful material for Plone 2.1 and 2.5 sites.
