I can see how manual SELECTand UPDATEslow down as they grow and the growth of the table, but what about INSERT?
SELECT
UPDATE
INSERT
INSERT also slows down especially if you have a lot of indexes which also need to be updated.
However, there is a difference between different storage systems: MyISAMfaster for a large number SELECT, InnoDB is faster for a large number INSERT/ UPDATE, because it uses row locking instead of table locking and the way indexes are handled.
