Try a test version that looks for more than one string. You'll have to run grep 50 times to find 50 strings, while a regexp loop will search each line for all 50.

The regexp loop should scale better for large numbers of regexps, too. Iterating a loop and searching for a pattern match are relatively fast, compared to reading information from the disk or spawning a subshell.
