Are indexing personal mail files or some other database types? The size will vary depending on the settings you apply. For example, the index of a database with 10,000 documents composed of one field containing 3 words probably wouldn't be very large at all. On the other hand, a database that has 500 documents each containing 5 word doc attachments could be enormous depending on whether or not you are indexing the attachment content.
I can't say what kind of performance hit indexing the files would be as I don't know anything about them but as long as you have a reasonably resourced server platform, it probably won't even be noticed. You can also set the indexing up to happen on a schedule (off-peak hours, etc.) but if you have databases that get updated a lot that likely won't be an option.
