I'm really only running a small and specific number of tests, one READ =
at a
time, files ranging from 8K to 256MB.  Is there any place I can read =
about
the reasons why my client (Linux 2.4) isn't using the blocksize I need?

Thanks,
Amir.

hi amir-

using "rsize=3D8192" means the client *can* use 8KB reads,
it doesn't mean that it *always* will.  there are a variety
of reasons the client might choose 4KB reads even though
it could send larger ones.

can you describe your workload?
