Not necessarily, what you are most likely seeing is the data for the
string being pulled in from main memory to the cache. Chances are that
if you do a strlen before accessing the string, the time for the string
manipulation will show up as something else if you remove the strlens,
but it probably won't make anything faster. What would make this faster
is getting the string data that is read sequentially closer together.
