Poor network performance

Use the information in this section to troubleshoot network performance problems, for example, slow response time.


Complete the following steps until the problem is solved:
  1. Isolate the network (such as storage, data, or management) that is operating slowly. Use ping tools or operating-system tools such as a task manager or resource manager to isolate the network.
  2. Check for traffic congestion on the network.
  3. Update the device driver for the node that is related to the NIC or for the storage device controller.
  4. Use the traffic diagnostic tools that are provided by your I/O module manufacturer.
