Do you hear that, Mr. Anderson? That's the sound of premature optimization . . .

The overhead in it being two regexen is so likely trivial as to not be worth the effort. Not to mention you could probably get more of a boost by rearranging the cases so the trivial presence of /,v$/ is checked first before bothering to go on to the user's regex.
