I think you may be best off with ToscaWidgets and Mako for this particular use case.
Mako has a lot more caching options, and the large number of widgets you're using highlights some of the performance issues that you may find in Kid when rendering large pages. We recently had to replace a kid template that was taking 9 seconds to render (it was one HUGE table) with Mako, and our render time droped down to 0.04 seconds. And it really didn't take that long either. If you have lots of widgets, and you can rewrite the widget templates in Mako (which requires ToscaWidgets) that will help a lot. TW should be useable in current versions of turbogears, but it badly needs some more documentation so you should expect to look at the source, or ask questions on the mailing list. --Mark On 8/14/07, Brian Cole <[EMAIL PROTECTED]> wrote: > I have a fairly static page containing many widgets (100+).
