It sure does, so my advice to you is to "grep smartly", so you narrow down your search as fast as you can, then pipe the results into another grep for processing. While experimenting with scripts, I have brought down my share of servers using grep only (but I can't resist huge one-liners).
Also, when you want an endless loop running, it might be wise to use the sleep-command to add in a pause of a few seconds, just to free up some resources.
