7. Click on “Run Tuning” button.
Clicking the "Run Tuning" button activates the general tuning as explained above and changes several
driver registry entries for the current adapter and its sibling device once the sibling is an Ethernet
device as well. It also generates a log including the applied changes.
Users can view this log to restore the previous values. The log path is:
This tuning is required to be performed only once after the installation is completed, and on one
adapter only (as long as these entries are not changed directly in the registry, or by some other instal-
lation or script).
6.1.4.1 Performance Tuning Tool Application
You can also activate the performance tuning through a script called perf_tuning.exe. This script
has 4 options, which include the 3 scenarios described above and an additional manual tuning
through which you can set the RSS base and number of processors for each Ethernet adapter. The
adapters you wish to tune are supplied to the script by their name according to the “Network
Connections”.

Please note that a reboot may be required for the changes to take effect.
