Dear ivanmarcus/mike,

The MSRDP setup is done at my end for testing purpose with same user ,same
screen,same depth etc. we measure the bandith for singile session and it is
too low. i am already sharing a snapshot in preious mail.

*My point is if i used MSRDP web client to acees the server it take low
bandwidth utilization . when i am using guacd with xrdp it uses high
bandwidth.*
