There is an art to making DB-bound applications run efficiently. The short of it is "Index, index, index".
Now, another solution would be to construct your data such that the hit pileups can be detected as part of a SQL query. This isn't as hard as it sounds. Take a look at the MySQL function COALESCE().
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
Please read these before you post! —
