I think that you are worried for nothing. First of all your database
seems to be small - less than half million records.
The main think that you have to do is to organize your indexes
correctly. I mean this: for good performance and high speed working of
yor database you must have indexes on every field wich you will use in
WHERE clauses or other conditions in your SQL's.
