I'd like to share something I recently found that made a huge
difference for me: scopecache custom tag. We used it to to cache
code fragments that were particularly slow. Now, we have these code
fragments including html and all loaded in RAM and our pages run a
million times faster. Before our site would get very slow when more
than a few users were hitting pages that required a lot of database
calls that ran hundreds of times inside a cfloop tag.
