Your query might be memory bound, but might not be. You've got to attain very high speeds to be memory bound. In your case, you chose a query that likely matches quite frequently, no? If so, it's certainly not going to be memory bound because of the overhead of dealing with all those matches. Try a literal that doesn't match or matches very rarely and you'll have a better shot at being limited by memory bandwidth. (But still maybe not.)
