Performance optimization tips
General performance optimization
The following suggestions apply to all operating systems:
●
Enable Advanced Video Compression (see Advanced Video Compression on page 25 for more
information).
●
Enable HP Velocity (see HP Velocity on page 25 for more information).
●
Do not use color or animated cursors on the sender. Although RGS displays color and animated cursors
very well, this typically requires more network bandwidth and CPU resources.
●
Set the sender desktop background to a solid color to minimize the amount of image data that needs to
be sent.
●
Set both the receiver and the sender display depth to 32-bits per pixel.
●
Lower the sender’s display resolution.
●
Reduce the Remote Audio quality setting in RGS Receiver, or disable Remote Audio if it is not needed.
The following suggestions apply to Windows only:
●
Increase the process priority of RGS Sender. See Setting the RGS Sender process priority (Windows only)
on page 22 for more information.
●
Adjust the Windows system performance settings in Control Panel. The Adjust for best performance
option will minimize the bandwidth requirements for RGS.
Network performance optimization
RGS depends on low network latency and reasonably high network bandwidth. There are several methods to
test and measure the network bandwidth, latency, and the number of hops between the receiver and the
sender:
●
Use the ping command to measure network latency.
●
Use the Traceroute (Linux) or tracert (Windows) command, which will report the number of hops
it takes to reach a computer in addition to the network latency.
●
Use the Test TCP (TTCP) tool, which is available at http://www.pcausa.com/Utilities/pcattcp.htm.
Once you’ve characterized your network performance, you can decide if improvement is required.
The network interface will auto-negotiate the network speed with the network switches on the local network.
Most modern network interfaces and switches will negotiate the highest possible speed available. However,
