1024 is not 1000

Well a byte is 8 bits. A kilobyte is a thousand bytes while a kilobit is a 1000
bits. A megabyte is a thousand kilobytes
Megabit per second - http://en.wikipedia.org/wiki/Megabit_per_second
Kilobit per second - http://en.wikipedia.org/wiki/Kilobit_per_second
when you transfer 100MB over a 1.5Mbit/s line you are transferring 100 x 1000 x
1000 x 8 bits over a network that can average a transfer of 1.5 x 1000 x 1000
bits every second
I think...

session bandwidth calculations
I'm currently in a battle with upper management about bandwidth consumption
with certain apps. I could use a basic defintition as what the differences are
from KiloBytes and Kilobits and MegaBytes and Megabits to demonstrate to
further elaborate. The confusion comes in when the idea of users transferring
files that are about 100 MegaBytes over a 1.5 Megabit line. This ties into the
justification of an additional citrix server if multiple users are running off
different apps, printing, file-sharing, etc. Thanks,

I am assuming the 27KB was bits not bytes, as 27 KBps = 216 Kbps...I
benchmarked a client/server app just recently. Heads down dataentry in the
application averaged only 26Kbps (no sound, 16 bit color,128 bit encryption,
seamless window) with v9.15.xxxx PNAgent.Benchmarks of ESRI ArcGIS were closer
to 33Kbps (probably because itis so graphics intensive).Printing can burst much
higher as indicated but can be limited (usingthe policy to control it in
Citrix) without much notice by the user. We limited GIS plotter users (who
could plot 40-50MB drawings) to30Kbps they didn't even notice. Printers are so
much slower than thenetwork it just sits in the spooler waiting to print vs.
sitting inthe plotter's local memory waiting to print. Net impact to the user
is the same.-MattOn 6/2/06, Landin, Mark <Mark.Landin@xxxxxxxxxxxxxxxx> wrote:>
