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
smal
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 a

AFAIK, the no. of flows here may not have to do anything with LLC. Also there
is EMC cache(8k entries) of ~4MB per PMD thread.
Yes the performance will be nice with simple test cases (P2P with 1
I guess the answer is now the general LLC is 2.5M per core so that there is
64k flows per thread.

Thanks Darrell,
More questions:
Why not allocating 64k for each dpcls? does the 64k just fit in L3 cache or
anywhere? how it is calculated in such an exact number? If there are more
ports added for polling, for avoid competing can I increase the 64k size
into a bigger one? Thanks.
