Windows Servers - Slow network performance

I have had many instances over the last few years of slow netowrk performance on various machines.

Here I list the items I have changed to resolve these.

1. Disable AutoTuningLevel

netsh interface tcp set global autotuninglevel=disabled

To re-enable AutoTuningLevel if it does not work 

netsh interface tcp set global autotuninglevel=normal

2. Disabling SMB 2

3. Disable TCP Offloading (needs restart)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Value = DisableTaskOffload
Type = DWORD
Data = 1

Value = EnableTCPChimney
Type = DWORD
Data = 0

Value = EnableTCPA
Type = DWORD
Data = 0

Value = EnableRSS
Type = DWORD
Data = 0

I have had SMB2 and the TCP Offloading sprt out various network performance issue over the years.
