what are you trying to tell us here?

do you REALLY believe you local disks can outperform a
SAN storage with 1 GB dedicated buffer cache und a
DEDUCATED 1400 MHz CPU which is only optimized for
one task: disk performance

you lcal storage has to fight for CPU and memory all
teh time with other applications (caching etc.)

to believe under really high load a local storage
is faster at the end is bullshit!
