But you are still doing that work for every request in your scheme, which if you have a high load won't necessarily give better performance.
Why not do a time-based cache that expires every second or minute, etc.?
I had been wanting to allow for asynchronous cache behavior and will look into it, but for now if you really want to go that way you'll either need to do it that way yourself, or write a custom transformer to do that as you proposed. I tend to dislike transformers with side effects in that sort of scenario, but it should work.

I realize my approach is somewhat reversed, however, in pages that are accessed and change often it seems like it might be necessary to obtain acceptable performance. For example, if I had a poll on a home page that changes every second or so, it would be a huge waste to output the current value of the poll (a single number) every time the page is accessed and then regenerate the xml for the whole page and then transform it all again. Rather, it seems that it would be much more efficient if the call to the database was put off until the entire page was transformed and cached first. I realize this is possible to do with cocoon with transformers, however I was curious if there was any way to do it with esql and xsp.
Please correct me if I am wrong, or if this added complexity for high traffic pages is not necessary.

It seems to me that cocoon would have to generate the xml output of the xsp page every time the page is called, and thus would be unable to cache any xsl translation latter? Is this true? If so would it not be a better idea to have the page be translated into html before all database code is called and then insert the database code at the very end and output as a jsp page or something?
Is that the way other server side frameworks do? Remember that the most
important thing is data, which is being generated at the beginning and then
the presentation is applied. Your approach is completely reversed.
Take look at Velocity - maybe it could solve your problems ouzo
