Grep is essentially the slowest way to search content. It has to read every byte. You can do much better with term/field indexing. Why would you be calling grep from an online application anyway?

Grep doesn't read every byte.

  I used the word "read" and not the word "compare" for a reason. You are missing the big picture here of linear search versus indexed search. Optimizations in grep don't magically make it better than O(n).
