Google compute engine GCE上的网络带宽应该是多少？

我想在europe-west1-a区域的google compute engine实例上使用icecast2服务器托管一个webradio电台。这项服务主要是带宽有限的，所以我搜索了文档，找到了可用带宽的估计值（从我的服务器到互联网），但我找不到它

我已经运行了som初步测试，在一台100 Mbps的bandwith远程服务器上用curl进程模拟侦听器。我的测试在500名听众中开始失败。流编码为64kbps，因此服务器输出约32Mbps。从测试运行的方式来看，我不能断定带宽是限制因素，但我仍然想知道估计我可以拥有的并发侦听器数量所需的带宽。

100兆位/秒。如果您是从单个主机进行测试，您如何知道瓶颈不是接收端，那么您的测试可能不准确

这是我的测试1 vCPU，3.8 GB内存GCE实例：

这些是兆字节还是兆字节？
