Hi, I'm doing some web development and have mysql (3.23.x) installed to test with (win2k, but I don't think this question is particularly platform specific).
I have a reasonably complex query which I am trying to optimise. When I first startup mysql, and perform the query, it can take 10 or so seconds. However, further subsequent queries (sorting by the same column) return in a fraction of a second. This is true even with new WHERE or LIMIT clauses. Is mysql creating a 'temporary' index and caching it? Is the original 10 second query the actual time for my query to execute? I'm finding it difficuly to optimise my query as I'm not sure exactly which times are correct. Hope I've explained this OK - sure I'm missing fundamental, so apologies in advance.
