If I am not mistaken -- I'm not very familiar with those things -- the
capability in question is a high-speed *seek* not a high-speed *search*.
That is, you can use the high speed only if you know exactly where you
want to go.  Unfortunately, tar doesn't; it really does have to read the
stuff going past to decide whether it's reached what you're after.
