Remote Desktop Gateway Optimization (Preliminary)

Donald Van Patten -

Remote Desktop Gateway Optimizations: 
  • RDG requirement is to use IIS, it also uses for Application Pools, and are inter-related.
  • As a result of inter-related application pools, IIS App Pool Recycling is turned on.  To keep RDG in memory, disable App Pool Recycling.
  • Optional Network Optimizations:
    • If using VMWare, use VMXNET3 (Do not use E1000 and E1000E)
    • Disable IPv6, QoS and anything that has to do with packet shaping.
    • If VMQ is enabled on the VMW Host/Guest, disable it.
    • Increase the Maximum Input and Output threads to allow for multiple TCP threads inbound.
      • HKLM\Software\Microsoft\Terminal Server Gateway\Maxiothreads (REG_DWORD) = 5
    • Increase those IIS Pool Threads: 
      • HKLM\System\CurrentControlSet\Services\InetInfo\Parameters\MaxPoolThreads (REG_DWORD) = 4
      • HKLM\Software\Microsoft\Rpc\ServerReceiveWindow (REG_DWORD) = 64kb
        • Adjust as need with the maximum of 1GB.
    • Disable TCP Offloading on the NIC: https://support.rackspace.com/how-to/disabling-tcp-offloading-in-windows-server-2012/
