Hi Zachary,
Your issue may be with the PCI-e 3, with 16 lanes Each slot is limited to
128Gb/s[3].
Now, AFAIK[1] the CPU is connected to the I/O with a single PCI-E slot.
Several thoughts that may help you:
1. You can figure out the max b/w by running netsurf over the kernel
interfaces (w/o DPDK)
Hi Alex:
Thanks for your help.
I forget to describe some criteria in my original post.
At first, I has confirmed my 82599 has connected by PCIe Gen3 (Gen3 x8) speed.
The theoretical bandwidth can support over 160G in total.
Hence, It should get full speed in my test.
Second, I have ever check
Hey Guys,
Recently, I have used l2fwd to test 160G (82599 10G * 16 ports), but I
got a strange pheromone in my test.
When I used 12 ports to test the performance of l2fwd, it can work fine
and achieve 120G.
But it got abnormal when I using over than 12 port. Part of ports seems
something wrong an
