How dynamic is dynamic?

When you say few minutes... are you talking their browsing time (where
they stare at content)... or is that real compute time?

Guessing that the dynamic pages are generated quickly and wisely...
easily support well into the thousands (even tens of thousands).
Could be more limited by your pipe size in fact.

All depends how much data and what kinds of data/queries are coming
out of the MySQL database.  Could be some php issues as well.. depends
upon the complexity.. doesn't sound like there's much complexity
though.

:-) I think there are some tools you can use to create the
queries in a scripted form... but nothing automatic since
it depends upon knowledge of your site, etc.
