I understand... However, can we control the irq / core distribution of flows as we can with RSS (using smp_affinity)?

Hi Moshe
RSS is an IP-based (IP+port for TCP) hw hash, if you need something more flexibly (e.g. a custom hash function) then you need zbalance_ipc.

Hi Alfredo,

1. You were abosutely right - that was the exact reason. Once I switched to single queue mode, everything worked as expected.
2. Given Intel's RSS functionality - what is zbalance_irq doing different ? Why should I use it instead of making use of RSS ?
Thanks !

Hi Moshe

 Hi Everyone,
I'm experiencing a weird situation where I'm running zcount twice:
1. zcount -i zc:em1
2. zcount -i em1
the first execution (zc mode) produces a count value of about 0.5 gbps while the 2nd execution (non zc mode) produces a value of about 4.5 gbps.
How is that possible ? what am I doing wrong ?
i'm using version 6.4.1-stable with 4096 ring slots and an intel 10g device (intel ixgbe 82599) on ubuntu 14.04.
Thanks in advance
