I am pleased to announce a new article on JSF Central. In the second installment of this two-part article, Dan Allen continues his discussion of some common performance problems you may encounter when using JSF components, Seam components, and the EL. You'll learn about the set of best practices for eliminating them that led to an improvement of two orders of magnitude in the performance of his application.

Here is an excerpt:

In the first part of this article, I began briefing you on optimizations I made to maximize the responsiveness of a JSF application that I developed out in the field. I cited performance problems caused by casually accessing components from a JSF view, then presented a set of best practices to eliminate this unnecessary overhead. Despite the progress made by the end of the first part, you had not yet witnessed the two orders of magnitude in performance improvement that was promised.

In this part, the additional gains will be achieved by leveraging partial page rendering-provided by the RichFaces JSF component library and by slimming the response. Partial page rendering cuts out the overhead of rerendering the entire page after each user interaction, which turns out to be the real bottleneck in most traditional web applications, and instead redraws only the areas of the page that have changed. Naturally, you want the replacement HTML source to be as condensed as possible. These optimizations allow the responsiveness of a web application to measure up to its desktop counterpart.
