It'll be also great if you can attach more information in the cover letter
in the next post.  For example:

  - Per your investigation, what's the major influential factor for the
    memory updates?  Besides the number of devices, does the number of
    queues also matter?  Is there anything else?

  - Total downtime comparison (only if above is only part of the downtime)

  - The nic used in the test.

Thanks,
