Well as a general rule anything over about 80usecs for
InterruptThrottleRate is a waste. One advantage to reducing the
interrupt throttle rate is you can reduce the ring size and you might
see a slight performance improvement. One problem with using 4096
descriptors is that it greatly increases t
Here's what I did
ethtool -A p1p1 rx off tx off
ethtool -A p3p1 rx off tx off
Both ethtool -a and Arista that's pumping data show that RX/TX
pause are disabled.
I have two cards, each connected to a separate NUMA node, threads pinned,
etc.
One non-standard thing is that I use single queue only
When you say you disabled flow control did you disable it on the
interface that is dropping packets or the other end? You might try
explicitly disabling it on the interface that is dropping packets,
that in turn should enable per-queue drop instead of putting
back-pressure onto the Rx FIFO.
With
xoff was increasing so I disabled flow control.
That's a HP DL360 Gen9 and lspci -vvv tells me cards are connected to x8
link, speed is 5GT/s and ASPM is disabled.
Other error counters are still zero. When I compared rx_packets and
rx_missed_errors it looks like a 38% (!!) packets are getting los

Hello.
On my IDS workload with af_packet I can see rx_missed_errors growing while
rx_no_buffer_count does not. Basically every other kind of rx_ error
counter is 0, including rx_no_dma_resources. It's an 82599 based card.
I don't know what to think about that. I went through ixgbe source code and
