8 Performance optimization

General

The following suggestions apply to all operating systems:

●

Enable HP Velocity (see HP Velocity (Windows/Linux only) on page 28 for more information).

●

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.

●

Increase the Max Image Update rate from 30 to 60 using the RGS Sender Conguration tool.

●

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 25 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

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,

unless the network has been carefully designed for maximum throughput, the network interfaces and

switches might auto-negotiate to a sub-optimal speed.

If the network interface and switches are congured to auto-negotiate properly, you can leave the settings to

auto-negotiate. If you want to force the network to operate at a particular speed, the settings in the network

interface and switches can be hard-coded. You must be careful with these settings, however. If the network

interface and switch settings don’t complement each other, the network will have poor performance.

To congure a network interface to force a particular network speed on Windows:

1. In Control Panel, select Device Manager.

2. Expand Network adapters.
