If you mean the file size, then it's a bit of a silly question - it's going to depend on too many factors. Firstly, are you fetching anything else from the same row of the database? For example, if you are fetching the file path from the DB already, then it will take a trivial extra amount of time to add the file size to that request, while fetching it separately from the folder structure will add seek times and so forth making that likely to be a longer operation.

Secondly, there is the accuracy problem: how up-to-date does the size have to be? If the file is unchanging between the file info being written to the DB and when the info is read out, then it isn;t a problem. But...if the user can update the file in any way after the info is written, then it can quickly become useless.

Sorry, we can't make that decision for you - you will have to look at exactly what you are trying to achieve and work from there.
