I recently took over support for a large website that uses Radiant. Over 1000 pages and added/edited all the time.
The site has a sitemap page, which shows all of the available resources. The sitemap is generated using the navigation_tags extension: <r:nav root="/" depth="4" expand_all="true" /> It takes forever (~25sec) to generate that one page due to the recursive nature of the calls. Are there any faster alternatives to this extension? Open to any suggestions...
