Using Remote Graphics Software

Setting the Windows Sender Process Priority

This section describes how to adjust the process priority of the Windows Sender. The default process priority of the Windows Sender is normal. Under some situations, however, increasing the process priority of the Windows Sender may improve interactivity. In some cases, the Windows operating system scheduling algorithms do not give the RGS Sender sufficient CPU time to maintain smooth interactivity. Erratic updates from a Windows Sender can sometimes result from a process load and scheduling situation. (Networking performance can also contribute to poor interactivity.)

RGS Sender for Windows on some laptops has exhibited erratic behavior. Increasing the Sender priority to high usually improves interactivity in this case. This enables the Sender more frequent access to the CPU and improve updates to the Receiver.

Process priority for the Sender is command-line accessible for the Windows Sender. Four command-line options are available: -belownormal,-normal,-abovenormal,or -high. Priorities low and realtime cannot be selected for the Windows Sender. Please see Command Line Options for further information.

Currently, there are two ways of setting the process priority for a Windows Sender:

using regedit to modify the rgsender service start up parameters in the Windows Registry

using HP Performance Tuning Framework (PTF) to configure Windows Sender priority (available only on HP Workstations)

Both methods are covered below.

WARNING: Adjusting the process priority of the sender to a level higher than - normal can cause other normally privileged processes to get fewer CPU cycles than usual. Please adjust the priority of the sender with caution.

Setting the Sender process priority using regedit

This section describes how to use the Windows regedit command to increase the process priority of the Sender service when it starts. Under normal operation the Windows Sender runs as a Windows Service. When the system starts up, the installed services are usually started. When the RGS Sender is installed an entry is added in the Windows Registry for the Remote Graphics Sender service. regedit can be used to modify the command line that is used for starting the Sender service:

1.Start regedit - this can be done by opening a Windows command prompt and executing the command “regedit” or using the "run" command line from the Start menu

2.Using regedit navigate to the key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\rgsender
