Hi, I had used this paramter in dpdk section for vpp startup.conf. I am debugging vpp performance and I use all vpp default plugin and node. I need more methods to monitor vpp performance and optimize them. ------------------ Original ------------------ From: "Benoit Ganne (bganne) via lists.fd.io"<[email protected]>; Date: Thu, May 7, 2026 08:42 PM To: "[email protected]"<[email protected]>; "Feng Lei"<[email protected]>;
Subject: Re: [vpp-dev] tx mode is scatter and is not vector Hi, > But dpdk by vpp booting, using `--in-memory -a pci xxx`, will find tx is scatter and not vector. You probably need to add no-multi-seg in your dpdk startup.conf section: https://s3-docs.fd.io/vpp/26.06/configuration/reference.html#no-multi-seg DPDK vector rx/tx flavors usually cannot support chained buffers so you have to explicitly disable them. This is usually fine if you do not expect jumbo frames. Best ben
