should this view be optimized?

I have a survey application with he following models:

Surveys has_many Questions Questions has_many Answers

When a user takes a survey, they call take_survey and it renders a collection of partials _survey_questions. These questions are set to display:none and revealed using an AJAX call to 'reveal_next_question' and page.show. It also calls an extra load for images as I am using FlexImage. Are CACHE hits free or am I doing things wrong? I am having trouble interpreting the output from the Mongrel terminal:

take_survey METHOD

It can probably be optimized, but if you're not experiencing any performance issues then optimization may be premature and of little value.

Cache hits aren't as expensive as executing the actual query, but they aren't exactly free either. It should probably be possible to bring the number of queries down.
