It's possible. There are parallels between main memory and disks. A disk seek gets you hundreds or thousands of bytes and requires (blocking for) millions of cpu cycles; a cache line fill gets you 64 (sometimes) bytes and requires (spinning for) hundreds of cpu cycles. You want to minimize both of those, but with memory, the difference is much less dramatic.
