说起来我这个缓存百分比这么低，这正常吗？难道是因为论坛里的内容太少了没什么需要缓存的？

差不多是这样的。

我们的缓存比率也很低。

我这是因为 cdn 了 cloudfront 的原因？……

这个就不是很清楚。

可能不同的网站缓存的情况不意义，同时和内容也有很大的关系。

也没有特别在意这个数值。

我觉得我们这个数值比较低的原因是 CDN，我们 CDN 用的是 AWS，这个域名没有再用 CloudFlare 进行缓存了。

这几天调整下，可能会有些变化。

看了下 AWS，数据传输也还行。

不是特别清楚 CloudFlare 的缓存算法是什么。

但这个缓存的比率，我们也没有办法调整。

今天我这缓存比率上来了点。

CloudFlare 当设置成功后，应该不是马上生效的，还需要等一些时间才可以。
