> From dev ml (Todd Benge)
> There are several steps we are taking to improve the overall
> system performance, one of which was to look at the displaytag source
> code. In doing so, we were able to make a couple of significant
> changes that have made a major impact on overall performance. So far
> the changes we've made have not had any impact on functionality but we
> do not use the el tags or velocity templates. We've tagged all of the
> changes in the source files with my name (Todd) so that you can
> evaluate the changes. The attached jar file includes the source files
> changed as well as the Borland Optimizeit profiles taken before and
> after the work was completed. You should see that the processing time
> spent in the tag libraries and main JSP is significantly reduced.
> This is mostly due to caching of previously reflected methods and the
> removal of the iteration in the doAfterBody of the TableTag. If the
> changes look reasonable, we'd be happy to commit the changes back to
> the community. The two authors of the changes are Todd Benge and Matt
> Green.
