很多人购买VPS的时候，往往是光注意价格，忽略了商家TOS里的一些限制。搬瓦工VPS在TOS里有对各个套餐的CPU限制有一个明确的说明，有些朋友不注意这些，就导致自己的VPS被告警甚至限制CPU负载。当然有一点不用担心，CPU触发警告不算在三次警告暂停VPS里面，只是警告然后限制CPU峰值而已。
搬瓦工的VPS允许CPU突发高负载，但是1小时的平均负载不能超过限制值，（TOS原文：We allow to max out CPU for short periods of time. However, please make sure that 1-hour average CPU load does not exceed the following levels:）具体的限定值如下：文章源自搬瓦工-https://www.bwhcn.com/1655.html

一旦VPS长期高负载的使用CPU，CPU会被自动限制到上面的数值。所以如果有必要的话，建议购买稍高配置的VPS。
