Have you ever tried making 4 equal partitions on a hard disk (or just 2 small
ones the same size on the outer and inner cylinders), and done hdparm -t tests
on them to check read speed?

The speedup is signifigant, which makes me think it might work on cdroms as
well.  So if you can get all your files you want preloaded into cache to get
read in a single big chunk from outer cylinders, maybe...?

But no, thats definately an optomization to worry about a long time from now.
