Thanks Jeremy.

 

I quickly checked per-patches results and logs for the failures. That seems not always failed case.. like fluctuation.

 

For this case, could you help to check

- if BIOS’s turbo boost is off, C0/C1 is off, C6 is off

- if cores’ are isolated in kernel’s parameter

- if other tasks are scheduled on the testbed when running performance test

 

If all settings are good, we may consider it’s a regression or unstable performance issue. We will double check the performance by IXIA with latest DPDK master when we back to office (1 week later).  

(replaced jeremy @mail with the dpdklab alias).

Is this issue linked to the failures I see?
