亚马逊EC2的传输率很低

我有一个关于亚马逊EC2传输速率的问题。 基本上我正在评估转向亚马逊堆栈的服务，但是我们希望首先将其与当前的设置进行基准比较。 我的设置非常简单，我只有一个大的EC2实例运行访问一个小的RDS实例，两者都位于欧盟西部区域。 在EC2实例上，我正在运行股票apacheconfiguration文件，而在我当前的服务器上，我正在运行修改后的apacheconfiguration文件。 这意味着我期待更less的并发连接，但我期望传输速率是相似的。

我正在运行的基准testing是没有什么是沼泽标准ab（apache基准testing）

ab -n 100 -c 10 http://www.example.com/

EC2上的设置导致以下结果：

• 我可以对Amazon Beanstalkconfiguration进行哪些持续性更改？
• 使用Capistrano中的Amazon EC2工具来获取服务器来推送代码
• EC2 Linux AMI与ffmpeg（no yasm？）
• 在EC2 Micro上的Resque（Redis）复制到3个可用区域
• 无法从笔记本电脑连接到RDS（amazon web services）上的MySQL

而我的服务器回应这个：

有谁正在经历这些低传输率？ EC2实例是否正常？ 我可能做错了什么？

如果您需要更多的信息，请让我知道。

感谢你的帮助。
