我有一个使用https将JavaScript文件传输到客户端的网站。该网站为getsimpleapps.com。
事实证明,使用https(20.08s-29.08s)加载此文件的速度比使用http(380ms)慢52倍。
该网站的首页与javacript文件共享相同的慢度。
我最近从Dreamhost切换到了linode,并且骇入了让SSL在新服务器上运行直到实现的目的。我没有进行任何疯狂的配置。
linode运行Ubuntu 12.04,并且该站点位于(LAMP)堆栈的顶部。
我对堆栈溢出社区的问题是:如何在服务器上修复SSL和HTTPS?我知道栈溢出到处都是关于HTTPS速度慢的问题,但是没有给出真正的解决方案。ubuntu教程或配置指南将是理想的选择。

-嗯?请问您能在那里再次检查单元和语法吗?那没有多大意义。
