Its late, I'm tied and I'm frustrated at your ability to miss the

Regardless of whether you choose to measure latency or CPU load
if you test two read sizes (st_blksize and st_blksize - 4) you
will not be able distinguish between the two read sizes due to
the influence of other factors.

Regardless of
whether you choose to measure latency or CPU load
if you vary the st_blksize as specified in the previous email,
you will not be able distinguish between the two values of
st_blksize due to the influence of other factors.
What are you talking about? How can one vary st_blksize or choose a
preferred value for it?
