The performance tag has over 5000 questions which is also the master tag of 4 other tags. It can also be considered a "meta tag", much like previously burninated tags such as [naming] and [refactoring]. Also, as brought up in this post just recently, it can be confused with time-limit-exceeded, despite some of their somewhat specific differences. For performance in particular, it can still be implied in every question as it could still be brought up in a review.
Should we get rid of this one, or could there somehow still be some use to it?
