[dpdk-users] Very slow upload speed with VPP

[dpdk-users] Very slow upload speed with VPP

[Daniel Bush]

Hello,
I am preparing a system in order to aggregate multiple broadband connections and thus have set up a box (currently running gentoo, though same results achieved running under ubuntu 18.04) to run my existing circuit through until the fiber circuit arrives.
I have been able to successfully configure the box creating a host interface that is bridged over to GigabitEthernet1/0/0 allowing access to the usual apps and kernel.  However, when I run speedtest-cli through a capable server my downstream performance is equivalent to what kernel networking would provide and my upstream is nowhere near what kernel networking can provide at 3.80/mbps up.  Kernel or any other computer on the network would provide 40 mbps up and the fastest desktop would provide 700+ mbps down.  VPP matches what the kernel would provide on my testing system @ 560 mbps up.
System is a Xeon E3-1220 system with 16 GB.
