- For unstable connections, low throughput, or latency spikes, try increasing the
IRPStackSize. This registry setting increases the number of stack locations available for
the Input/Output Request Packet (IRP) stack. Increasing this number might lead to
improved network performance and throughput.
Using the registry editor, locate the registry subkey
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Par
ameters
If the IRPStackSize entry is not present, create a DWORD value with the name
IRPStackSize. If it is present, simply modify it. The default stack size is 15 (decimal), and
the maximum is 50. Microsoft recommends no using values between 33 and 38. Consider
trying values such as 20, 30, 32, 45, and 50. Once modified, the system must be restarted
to take effect. See picture below.
