foreword
With so many CDNs, which one has the best experience? Today, let’s briefly compare the gap between free CDNs and see which one is the most suitable for free prostitution
Baidu CDN
Official website: https://su.baidu.com/Average
speed 62.7ms, 需要备案only the domain name, 支持SSL, 流量5G/天(fast domestically, not slow abroad)
CloudFlare
Official website: https://www.cloudflare.com/Average
speed 111.5ms, you need to change DNS to it, 支持SSL, 无须备案, traffic is unknown (domestic is slightly slow, foreign countries are fast)
rain cloud
Official website: https://www.rainyun.com
Average speed 172.9ms, use its host, use CDN for free, otherwise 0.3/G, slightly slower than cloudflare. (Off-topic, the host is a few dollars a month, cheap)
Qiniu Yun
Official website: https://s.qiniu.com/zI7Rz2
Average speed 58.9ms, 10G of free storage and 10G of CDN traffic per month, Qiniu Cloud also has many overseas acceleration nodes, 国内必须备案,支持SSL
other
Others are not introduced mainly because there are many fee pits, such as Ali, Tencent, Huawei, etc., and the acceleration effect is very good, but the charges are different, such as the number of http requests, and the acceleration is also charged according to domestic and Asia-Pacific, not global acceleration. (However, if you only have domestic access, you can still give it a try)
in conclusion
If it is a small website that has been registered in China and the traffic is not very high, Baidu CDN is the first to be recommended, and then Qiniuyun. If there is no filing, choose CloudFlare.
