网吧用简单队列做限速完全是扯蛋。网吧限速最好的办法应该是带宽均分，然后在用简单队列来限制上传。在利用小包优先来处理游戏卡的问题。经过2个网吧，一个月的测试，完全摆脱了到处喊卡的噩梦，现在把经验发来大家分享一下。
ROS不要用简单队列来限速，什么智能动态限速也不要用。只需要用小包优先+带宽均分+简单队列限制上传速度。
小包优先的脚本如下：
/ ip firewall mangle
add chain=forward protocol=tcp tcp-flags=syn action=change-mss new-mss=1440 comment="" disabled=no
add chain=forward p2p=all-p2p action=mark-connection new-connection-mark=p2p_conn passthrough=yes comment="" disabled=no
add chain=forward connection-mark=p2p_conn action=mark-packet new-packet-mark=p2p passthrough=yes comment="" disabled=no
add chain=forward connection-mark=!p2p_conn action=mark-packet new-packet-mark=general passthrough=yes comment="" disabled=no
add chain=forward packet-size=32-512 action=mark-packet new-packet-mark=all passthrough=yes comment="" disabled=no
add chain=forward packet-size=512-1200 action=mark-packet new-packet-mark=big passthrough=yes comment="" disabled=no
/ queue tree
add name="p2p1" parent=wan packet-mark=p2p limit-at=2000000 queue=default priority=8 max-limit=6000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no
add name="p2p2" parent=lan packet-mark=p2p limit-at=2000000 queue=default priority=8 max-limit=6000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no
add name="ClassA" parent=lan packet-mark="" limit-at=0 queue=default priority=8 max-limit=100000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no
add name="ClassB" parent=ClassA packet-mark="" limit-at=0 queue=default priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no
add name="Leaf1" parent=ClassA packet-mark=general limit-at=0 queue=default priority=7 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no
add name="Leaf2" parent=ClassB packet-mark=all limit-at=0 queue=default priority=5 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no
add name="Leaf3" parent=ClassB packet-mark=big limit-at=0 queue=default priority=6 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no
然后是带宽均分：
/ ip firewall mangle add chain=forward src-address=192.168.0.0/24 \
action=mark-connection new-connection-mark=users-con
/ip firewall mangle add connection-mark=users-con action=mark-packet \
new-packet-mark=users chain=forward
/queue type add name=pcq-download kind=pcq pcq-classifier=dst-address
/queue type add name=pcq-upload kind=pcq pcq-classifier=src-address
/queue tree add name=Download parent=lan max-limit=10M
/queue tree add parent=Download queue=pcq-download packet-mark=users
/queue tree add name=Upload parent=wan max-limit=9M
/queue tree add parent=Upload queue=pcq-upload packet-mark=users
请根据直接实际修改IP地址段，下载最大速度，上传最大速度,lan为我连接内网的网卡，wan是我连接外网的网卡
限制上传速度的脚本：
:for aaa from 5 to 253 do={/queue simple add name=(yp . $aaa) dst-address=(192.168.0. . $aaa) limit-at=10000000/3000000 max-limit=10000000/3000000}
如果是3.2版本的，这个脚本自己要修改下，
就用这3个部分，别的不需要的，绝对比什么智能动态限速好的多.
