hi amos , thanks alot .

im trying to understand the calculation equation why it is as the formula u
posted above ??
not understanding ,
""bytes from client ""
from client to wt ?? from client to squid ?

==================================================
can i calculate the speed savings??

i mean that i want to calculate the bw over speed not over bytes

also i want to see this saving every 60 sec
is that possible ?
===========================================
i use mrtg monitors and usually i have basic snmp on interface
i look at traffic speed between "in" , "out" , speed"in"-speed"out"=speed
saving ( i know its not accurate)
my question is does my calcultion bw saving speed containg a very error
value ?
assume i have 700Mbps pumped to squid.
=======================================================
