Initially EMC had 1024 entries and the patch [1] increased it to 8k. By doing
so in simple test
scenarios, most of the flows will hit EMC and we can achieve wire speed for
I am interested about how to define 'reasonable' here, how it is got and
what what is the 'many case'? is there any document/link to refer this
information, please shed me some light.

Thanks Bodireddy.
Sorry I am a bit confused about the EMC occupied size per PMD, here[1] has
a different story.
Do you mean in real scenarios OVS-DPDK can be memory bound on EMC? I
thought EMC should be totally fit in LLC.
If the megaflows just part in LLC, then the cost of copy between memory
Q: “how it is calculated in such an exact number? “
A: It is a reasonable number to accommodate many cases.
Q: “If there are more ports added for polling, for avoid competing can I
increase the 64k size into a
bigger one?”
A: If a larger number is needed, it may imply that adding another PMD
I guess the answer is now the general LLC is 2.5M per core so that there is
64k flows per thread.
