[vpp-dev] Regarding vlib_buffer_t metadata

Hi, I am writing a plugin node which will get packets the usual way. I will pipeline these packets between my worker threads (in the same plugin node) using the handoff mechanism available. Thus, when my plugin node gets a packet, it could have been from an internal handoff from one of my

Re: [vpp-dev] Incrementing node counters

You’ll have to look at the instruction stream in gdb or else “gcc –S” and look at the generated assembly-language code. Even at that, the difference in clock cycles won’t be completely obvious due to subarchitectural CPU implementation details. “Node” is not a typical hot variable which would

Re: [vpp-dev] Incrementing node counters

Thanks for the comments. I know is_ip6 will be optimized by complier. I am still wondering how different between using xxx_node.index and node->node_index. Anyway,thanks, now I understand it is a performance consideration. Best Regards, Kingwel 原始邮件 主题： RE: Incrementing
