"Yes, actually -- turns out that the cost of a cache miss is *more* than the cost of compiling a template (we profiled this about a year ago, so it may have changed in the meantime). So it turns out it's easier to just parse the template when it's needed." This made me think about the more general question: When is it appropriate to cache a page or object? How many cache hits does it take to make up for the cost of caching? Obviously this depends on the complexity of the cached object -- say we cache the result of a rather simple function which includes one or two sql queries (using memcached): How many cache hits would it take for this to make sense?
