> Rarely do we consider how one query or a series of queries could interact to slow down the whole site. That doesn't seem right to me. It's almost always something to consider when designing the data model. Maybe I'm being uncharitable, but this seems to me to be equivalent to claiming we rarely consider the use of an algorithm or interactions between algorithms and data structures when writing some code. I mean, for toys that's fine, but I wouldn't defer this discussion for something I intended for public use.
