Hi,

I understand that DPDK should use the physical core. But here is what we te=
sted:

-          Enable HT

-          Assign 8 cores of the CPU (an 8-core Sandybridge CPU) to DPDK.

Surprisingly enough, we noticed that the remaining 8 cores (b/c there are t=
otal of 16 cores after HT) can still handle other Linux processes which are=
 SIP based signaling transactions.

Anybody can shed some light on how this worked? Is there anybody tried simi=
lar thing? What has been your experience?

Thanks,
-Jane
