This is sort of true.  Steve's test will tell you what
you can currently achieve based on your current
system.  File system and/or kernel restrictions may
limit what is actually possible on the platform.

eg a stock-standard newfs on Solaris will typically
limit you to 256k; playing with maxcontig can lift
that (or raw does away with all that nonsense
altogether)
