问题描述
我在3个Standard_A3上具有Azure Web角色. Web API负担很重，它可以传输许多大型对象.我试图找出可以达到网络带宽限制的RPS.有没有办法找出答案.
I have an Azure web role on 3 Standard_A3s. The web api has a heavy load and it transfers lot of large objects. I am trying to find out at what RPS we might hit network bandwith limit. Is there a way to find this out.
推荐答案
最大网络带宽是每种VM类型分配和分配的最大聚合带宽.最大带宽为选择正确的虚拟机类型提供指导，以确保有足够的网络容量可用.在低"，中"，高"和非常高"之间移动时，吞吐量将相应提高. 实际的网络性能取决于许多因素，包括网络和应用程序负载以及应用程序网络设置.
Maximum network bandwidth is the maximum aggregated bandwidth allocated and assigned per VM type. The maximum bandwidth provides guidance for selecting the right VM type to ensure adequate network capacity is available. When moving between Low, Moderate, High and Very High, the throughput will increase accordingly. Actual network performance will depend on many factors including network and application loads, and application network settings.
一个用户使用iPerf尝试了解两个相同大小的实例之间的网络性能.这是他有关网络带宽的结果:DS1 = ~741 Mbps DS2=~1.5 Gbps DS3-DS5 = ~2.8 Gbps DS11=1.5 Gbps DS12=~2.6 Gbps DS13-15 = ~2.8 Gbps
One user used iPerf to try to get a feel for the network performance between two instances of the same size. Here are his results about network bandwidth:DS1 = ~741 Mbps DS2=~1.5 Gbps DS3-DS5 = ~2.8 Gbps DS11=1.5 Gbps DS12=~2.6 Gbps DS13-15 = ~2.8 Gbps
在我看来，肯定有3个级别，但它们似乎与广告中所描述的不匹配.看起来某些标榜为高"的VM的速度可与极高"相提并论.可能尚未记录到性能的提高.当然，由于网络共享并且他们的结果可能会有所不同，他们实际上并没有公布这些速度，但是至少您对期望的结果有一个大致的了解.Moderate ~750 Mbps High ~1.5 Gbps Extremely High ~ 3 Gbps
There definitely seems to me 3 levels, but they don't seem to match what is advertised. It looks like some VMs advertised as "High" are getting speeds comparable to "extremely high". There might have been a performance increase that just has not been documented yet. And of course they don't actually advertised these speeds since the network is shared and your results may vary, but at least you have a general idea of what to expect.Moderate ~750 Mbps High ~1.5 Gbps Extremely High ~ 3 Gbps
