# 计算吞吐率的方法
两次调用计算rx packets 增长值，并除以时间间隔：
{ printf "\033[7m$(date +%T)/%-22s%13s %18s %10s\033[m\n" $(strings /bin/vpp|awk '/built.by/{gsub(/\./,"",$2);print substr($2,1,7)}') rxKpps/pktlen txKpps/pktlen dx_pps >&2
vppctl show int; sleep 2; vppctl show interface; } | sed -r 's/^([^ ])/\n\1/;s/\r//g' | awk 'BEGIN{RS="";u=2002;}/packet/{
