Some CMS's have options or plug-ins to generate static html and present that, instead of re-building each page from the database each time it's requested. Usually for performance reasons. Doesn't yours?
Front end performance hasn't been the biggest issue for me in this case.
The back end slows when there are page lists to load, modules/plugins to manage, etc.
One option I have is to convert this CMS to another - that may have less memory requirements - but converting lots of pages, even few pages, from one to another is often not simple and may not be worth it unless the destination CMS is sure to be superior.
@Renegade: Thanks. Teleport Pro seems a good option to create a local copy, that's what it does if I am right?
The bulk of the work is to re-create web pages based on a template. I need a template-based setup for future pages and edits. I am hoping to convert the content portion of the existing database to something (csv or sql) that can be fed to a template based local program.
