I'm playing with the distributor example application from dpdk 19.05.0 I have
three machines connected sequentially with an UTP Ethernet cable. The
middle is Ubuntu 18.04.2 LTS with a eigth core Intel I7 processor and 24 GB
ram. The eth device used is Intel I350 with four ports.
The strange behavior I'm observing is when I ping the second node from the
first node (traffic passing through the distributor) there are always one or
two packets lost.
When I use
l2fwd or
basicfwd applications there is no packet loss. Anyone knows if this is normal
or if it is not - what I'm doing wrong?
Another thing I noticed is that the ping replies come to the first node with
around one second of delay. (1024ms on most packets) Again there is no latency
with the basicfwd (packets arriving in 0.101 ms there). Is there any way to
minimize this delay in distributor application also?
