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
