根据流量限速的又一办法

关于此脚本的说明
首先是看了kuwin“的文章，我尝试做了流量监视的脚本限速，但是发现当流量变化大时，几个脚本同时运行，得出来的单机限制不一致，不知道算不算BUG，另外每运行一次脚本，CPU都是100%的，好怕死机
然后就想能不能用脚本关闭已经运行过的的流量监视，比如说流量大于6M时，脚本就关闭前面4M，5M的监视，但是现在还没办法解决。
后来看了yiguangqiang88的文章，有个取值的代码，想到了判断规则是否需要更变的方法，因为同一个流量监视动作时，限速脚本不会重复运行，而且一旦多个脚本同时运行时如果得出来的单机限制不一致，脚本再次本激活时会自动修正，
如果规划的速度等级多点，脚本确实是复杂点，不过效果还是不错的，另外如果没有限速规则更改的动作，CPU的占用率也低许多，我的是C3 1。0G，在多个脚本被激活的情况下，没有限速规则更改的话，占用率大概是20~35

楼主的研究精神值得学习，我现在用的是固定限速。你的方法可以采用一下。

wbyz20 发表于 2008-1-26 18:21:24

我用的是PCQ，但是上行一直不理想。上行好你限不了。
