EC2 - 微实例 - 网络响应/延迟/延迟非常慢

Question

我的一个例子是有一些不寻常的问题.Ping任何网站都非常慢.试图保持SSH连接也很糟糕.

以下是对雅虎的ping.知道是什么原因引起的吗？

我对EC2微实例的印象不一定是网络问题,但CPU循环本身.我想在micro实例中,您正在从虚拟机上的其他实例接收剩余的CPU周期.因此,虽然随着时间的推移,您可以获得保证的平均CPU周期数,但在短期内,您可以使用它们而不是拥有恒定的CPU功率.所以,我的猜测是,当你有CPU周期来响应ping时,可能已经太晚了.因此,网络旅行时间不是问题,但总体响应时间是.无论我在这里说什么都是我的猜测,可能无法反映真实情况.
