I read a bunch of articles and talk to developers about software performance and the word performant comes up quite a bit. You'll hear it mentioned conversationally (in technical conversations) like I've heard that kind of sql query isn't very performant or To make this code more performant, you should do xxx. The problem is that performant is not a word. I know this is a bit silly, but it does seem to grate on me (more than it should).
