Hi,
(Sorry had to resend this to some recipients due to mail server problems).

Just confirming that I can still reproduce the regression with single core and 64B frames on other servers.

Hi,
Adding Ferruh and Zhaoyan,

Ali,

You reported some performance regression, did you confirm it?
If I get no reply by monday, I'll proceed with this patch.

Sure I'll confirm by Monday.

Doesn't the regression also reproduce on the Lab's Intel servers?
Even though the check iol-intel-Performance isn't failing, I can see that the
throughput differences from expected for this patch are less than those of
another patch that was tested only 20 minutes earlier. Both patches were
applied to the same tree:

https://mails.dpdk.org/archives/test-report/2021-January/173927.html

quoted

| 64         | 512     | 1.571                               |

https://mails.dpdk.org/archives/test-report/2021-January/173919.html

quoted

| 64         | 512     | 2.698                               |

Assuming that pw86457 doesn't have an effect on this test, it looks to me
that this patch caused a regression in Intel hardware as well.

Can someone update the baseline's expected values for the Intel NICs and
rerun the test on this patch?

Thanks,
Ali
