default and with two reduced bandwidth settings (connection speed setting of
1Mb with 15- and 8-bit color) on a Windows XP target server (1024x768

With the reduced bandwidth settings, bandwidth is reduced significantly for
virtually all tasks. With the 15-bit color setting, perceived performance is similar
to the default parameters. Further bandwidth reductions are possible with
additional changes in the settings.
Please note that these bandwidth figures are only examples and may vary from
those seen in your environment due to many factors.
