Sounds like you have tests that need to read (probably cached) data files while the parent poster has tests that need to write to disks (probably in a database transaction). Those are different enough that run times won't ever be comparable.

I have tests that need to read. I have tests that need to write. All data written must also be read and verified. You're right, the data is probably cached.

If you need to access a database in your tests you're probably doing it wrong. Build a mock-up of your database accessor API to provide static data, or build a local database dedicated for testing.
