Very simple, I'd love to see caching functionality in the next big version after Gold. Should really help on high-traffic sites.
What kind of caching are we talking about here?
- Query cache, save query results so they can easily be re-used
- Flat file cache, that is, save entire pages in the cache until they get edited, then refresh
- Cookie based caching (you might already do this, though)
If you're not sure what I mean, tell me and I'll post some examples.
