echo 16777216 &gt; /proc/sys/net/core/wmem_max<br />
echo 16777216 &gt; /proc/sys/net/core/wmem_default<br />
这样设置之后在使用iperf3时限制速率为95兆来跑<br />
iperf3 -u -c <a href="http://192.168.XXX.XXX" target="_blank" rel="noopener noreferrer nofollow ugc">192.168.XXX.XXX</a> -b95M -t10<br />
如果不行的话就尝试<br />
iperf3 -u -c <a href="http://192.168.XXX.XXX" target="_blank" rel="noopener noreferrer nofollow ugc">192.168.XXX.XXX</a> -b100M -t10 -l314或者<br />
iperf3 -u -c <a href="http://192.168.XXX.XXX" target="_blank" rel="noopener noreferrer nofollow ugc">192.168.XXX.XXX</a> -b100M -t10 -l65507<br />
就是限制这个发包大小，具体多少就自己试一试了</p>
