Poor or slow Operating System performance

Use this information to troubleshoot Operating System performance issues.

  1. If you have recently made changes to the compute node (for example updated device drivers or installed software applications) remove the changes.
  2. Check for any networking issues.
  3. Check the operating system logs for performance related errors.
  4. Check for events related to high temperatures and power issues as the compute node might be throttled to help with cooling. If it is throttled, reduce the workload on the compute node to help improve performance.
  5. Check for events related to disabled DIMMs. If you do not have enough memory for the application workload, your operating system will have poor performance.
  6. Ensure that the workload is not too high for the configuration.
