Speed Performance with PXI-8231 or PXI-8232 Gigabit Ethernet Port

Hardware: Instrument Connectivity Other>>Ethernet>>PXI-8231

Problem:
In some situations the performance of the Gigabit Ethernet controller can be erratic on the PXI-823x products. This has been seen in cases where two computers are connected directly with two PXI-823x devices via a network cable. The erratic performance is a wide fluctuation in transfer speed versus payload size.

Solution:
To fix this problem, download and install the very latest driver from Intel's website.

See the related links below.

After installing the driver, do the following:
  1. Open the ProSet utility
  2. Click on the adapter
  3. Click the Advanced tab
  4. Highlight Interrupt Moderation Rate
  5. Change the value to Off
