Ethernet Performance Tuning
The user can configure the Ethernet adapter by setting some registry keys. The registry keys may affect Ethernet performance.
To improve performance, activate the performance tuning tool as follows:
Start the "Device Manager" (open a command line window and enter: devmgmt.msc).
Open "Network Adapters".
Right click the relevant Ethernet adapter and select Properties.
Select the "Advanced" tab
Modify performance parameters (properties) as desired.
On Intel I/OAT supported systems, it is highly recommended to install and enable the latest I/OAT driver (download from www.intel.com).
With I/OAT enabled, sending 256-byte messages or larger will activate I/OAT. This will cause a significant latency increase due to I/OAT algorithms. On the other hand, throughput will increase significantly when using I/OAT.
The user can configure the IPoIB adapter by setting some registry keys. The registry keys may affect IPoIB performance.
For the complete list of registry entries that may be added/changed by the performance tuning procedure, see MLNX_VPI_WinOF Registry Keys following the path below: http://www.mellanox.com/page/products_dyn?product_family=32&mtag=windows_sw_drivers
