在Jetty中缓慢响应Https [英] Slow Https response in Jetty

问题描述

我正在使用带有jetty 8.1.1的servlet 3和一个亚马逊ec2机器上的SslContextFactory（m1-small）。

I'm using servlets 3 with jetty 8.1.1 and the SslContextFactory on an amazon ec2 machine (m1-small).

• 来自localhost（amazone机器）的第一个HTTPS请求大约是150毫秒，而另外的
  请求似乎变得更快（低至~40毫秒），但没有接近
  的HTTP响应时间只有20ms - 为什么？加密真的是
  慢吗？

• The first HTTPS request from localhost (of the amazone machine) is about 150ms and further requests seem to get faster (down to ~40ms) but not as close as to the HTTP response time of only 20ms - why? Is encryption really that slow?

此外，当从亚马逊云外部比较HTTPS和HTTP
时，差异变得更加严重： HTTPS请求至少400毫米
慢！？怎么可能？加密内容是否也更大？并且
如何调试它或使其更快？

Also when comparing HTTPS and HTTP from outside of the amazon cloud the difference gets even worse: HTTPS requests are at least 400ms slower!? How can that be? Is the encrypted content also bigger? And how can I debug it or make all faster?

更多信息：所有'测量'是通过 time curl http://mydomain.com/ping 进行的，不可科学地完成，但可以重现。中间还有一个ec2负载平衡器。我确定我配置错了或者我有很大的误解。请告诉我！

Some more informations: all 'measurements' are unscientificly done via time curl http://mydomain.com/ping but are reproducable. Also there is an ec2 load balancer in between. I'm sure I've configured something wrong or there is a big misunderstanding from me. Let me know!

推荐答案

我需要了解如何启用SSL会话。为此，我创建了一个新问题，因为目前还不清楚如何在码头开启以及如何处理客户端一边

I need to find out how to enable SSL sessions. For this I've created a new question as it is unclear how to turn on in jetty and how to handle on the client side
