Configuration for Optimal Performance

You can have proxy installed on RPS or separately. However, for optimal performance, we recommend to put both on the same node.

Recommended configuration for proxy

• Architecture: 64 bit Windows machine. For more information about supported operating systems for Arcserve UDP, see the Compatibility Matrix.
• Memory: 8 GB or higher
• CPU: 4 cores
• Verify that the VHD file folder path is not compression enabled.
• When you trigger the Assured Security scan for the first time on the proxy server, by default, the new registry DWORD is created under the following path with value as 1:
• Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine.
• DWORD: Windows_Defender_Avg_Cpu_Loader
• If the registry value is 1, the CPU throttling value will be 90%. You can change the CPU throttling value using the following commands from PowerShell:
• set-mppreference -ThrottleForScheduledScanOnly $false
• set-mppreference -DisableCpuThrottleOnIdleScans $false
• set-mppreference -ScanAvgCPULoadFactor <PercentageValue>
• The CPU throttling value changes from the PowerShell commands only when the DWORD registry value is set to 1. If you set the DWORD registry value to 0, the next time you trigger the Assured Security scan, the CPU throttling value reverts to its default of 90%, and the registry value changes back to 1.
• Run Assured Security scan during non-peak hours or during weekends.
• The Assured Security scan relies on the AntiVirus (AV) engine scanning for its performance. We recommend that you do not run any concurrent operations during this task.
