I know MySQL is supposed to be extremely fast when it comes to running Select statements. That, that was one of the goals built into it from the start as a database for the Web environment.

Does that mean that its not so fast for running Inserts, Updates, and Deletes? Is there a comparison?

Just looking into building an application that I would prefer to platform independent with its own database rather then create modules for MS SQL Server, Oracle, etc... The application would make heavy use of Inserts and Updates.
