Disks use segmentation on their readahead buffers. Typically four-way. So they will only buffer four different chunks of disk at a time.
If you're reading from 50 different places on disk, the disk keeps invalidating readahead at the segment level. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
