Well I keep looking at the loadavg output from numerous tools and then in
my mind I divide by the number of processors, guess if any of the threads
would be doing I/O and if I cannot figure that out groan and run "vmstat"
for awhile to figure that out.

Lets have some numbers there that make more sense please.
