Hi Eelco,
These performance numbers were updated on the cover letter for the v8 of this
series as this was when some changes were made to the AVX code.
I didn't re run on v9/10/11/12.
However, I just re ran on the v12 and checked a few of actions (mod_dl_dst,
strip_vlan, mod_ipv4 4 x fields, strip_vlan + mod_dl_dst + mod_ipv4 4 x
fields), and compared with the v8 data to ensure consistency.
Performance results are < 1% delta from the v8 posted data.
Thanks,
Emma
