Let me tell the other story. Perhaps someone will know some details. When I tell it, usually to nontechnical people, I prefix it by explaining that UNIX has 3 different grep programs, all of which find text in files. There is regular grep. There is fgrep, the "fixed grep", which is simpler and only looks for basic text. And there is egrep, the "enhanced grep", that will look for fancy patterns and is very powerful. You would expect that fgrep, being the simplest, would be the fastest, but as it turns out, egrep is the fastest and fgrep is the slowest. One day at a meeting at Bell Labs, an MTS came rushing into the meeting, all out of breath. "Sorry I'm late, I was grepping my apartment for my keys." Dryly, the boss replied "You should have used egrep. It's faster."
