if two users are editing the same record at the same time, and the user who is second to save will inadvertently change certain fields in a record to a non current value, the the system will open up a dialogue box with the user to resolve the conflicts, field by field.
As for slowing down the save, i don't know, but I believe that the the form rules run in the browser, and they will run quite fast. I highly doubt that you would be able to measure the difference, but you could copy the form and try to do a timing test.
