We're using a CDN but when we look at the performance numbers it appears to be far less effective for mobile clients. We're considering disabling it entirely as we're not sure that it's worth it. Someone needs to build a special CDN for mobile, we'd definitely use that to improve latency!
我们都在使用CDN(Content Delivery Network,即内容分发网络),但当我们查看移动客户端的性能数据时,看上去优化效果远远没有那么明显。我们正在考虑停用针对移动客户端的CDN加速,因为我们不能确定它是否真的有加速效果。如果有人需要构建一个特殊的移动CDN网络时,我们会毫不犹豫地使用它来改善延迟!
The frequency with which I've been hearing this and similar arguments has been rapidly increasing as more teams are finally focusing on improving performance of their mobile sites. The problem is, while the statement is often based on real data (i.e. the relative performance improvements offered by a CDN are smaller for mobile clients), the conclusion is wrong: the absolute improvements are likely the same for all clients and hence worth every penny. Also, we don'
