Re: Info: NAPI performance at "low" loads

Manfred, could you please turn MMIO (you can select it
via kernel config) and see what the new difference looks like?

I am not so sure with that 6% difference there is no other bug lurking
there; 6% seems too large for an extra two PCI transactions per packet.
If someone could test a different NIC this would be great.
Actually what would be even better is to go something like 20kpps,
50kpps, 80 kpps, 100kpps and 140 kpps and see what we get.
