ClearCube Product Manual and Installation Guide
RDP allows several configurable capabilities. Enabling each additional capability
requires more bandwidth, thus impacting performance. The ideal I/Port performance
optimization process will lead to the best possible experience within any limitations of
your operating environment.
The following items can be configured prior to initiating an RDP connection:
•
Display: Desktop Size – Though RDP allows the desktop to be sized so that the
RDP connection runs in a window smaller than the local XPe desktop, anything
less than full-screen mode is not recommended for I/Port users.
•
Display: Color Depth – The color depth options range from 256 to True Color.
Generally, using only 256 colors negatively impacts the user experience, because
most images are grainy and low quality. 16-bit color is normally used.
•
Local Resources: Sound – Sound is configurable in three ways. Sound can
either be left at the remote computer so it plays at the source (the Blade). This
probably would not be done, since the Blades are in the data center. The other
two options are to ignore sound, or to redirect sound to the I/Port. This last option
provides the highest quality experience but also requires additional bandwidth.
If the user has limited bandwidth and does not require sound, this option can be
turned off.
NOTE: RDP provides downstream audio only. Upstream audio is not supported.
•
Local Resources: Devices – RDP allows local disk drives, printers, and serial
ports to be redirected. Again, these require additional bandwidth. Large quantities
of writes and reads from local disks adversely impact the performance of RDP.
Disk drive redirection does not have an overhead if the disk is not being used, and
can normally be checked safely.
If the user does not require printers or serial ports, it is best to disable re-direction
to prevent any potential bandwidth loss caused by the Blade OS carrying out any
sort of detection or other processes for these devices.
