使用更多的vCPU是否有助于提高node.js的性能? [英] Does using more vCPUs helps node.js with performance?

问题描述

我正在AWS ECS上的docker容器内运行node.js.我有一个过程.

I am running node.js inside of a docker container on AWS ECS. I have one process.

通常添加更多的vCPU，特别是在使用AWS ECS的情况下，是否可以提高我的应用程序的性能?

Does adding more vCPU in general and specifically in case of using AWS ECS makes performance of my app better?

如果我运行4个vCPU，我会看到CPU利用率比1个vCPU低得多，但不能保证将使用此备用CPU.

Cause if I run 4 vCPUs I see CPUUtilisation is much lower than with 1 vCPU but it doesn't guarantee than this spare CPU will ever be used.

vCPU与物理CPU有何不同?

And how vCPU is different from physical CPU?

推荐答案

使用容器的妙处在于，您可以在几秒钟内创建一个相同的容器，因此您无需放置额外的cpu即可处理窥视时间.您只需创建一个新容器并平衡流量即可.您只需要创建一个ecs服务，ecs就会负责扩展和负载平衡.

awesomeness of using container is you can create an identical container within seconds so you don't need to put additional cpu to handle peek time . you just create a new container and load balanced the traffic. you just have to create a ecs service and ecs will take care of the scaling and load balancing.

我不知道vcpu和cpu之间的区别.但1个vcpu = 1024个cpu单位.

i don't know the exect differens between vcpu vs cpu . but 1 aws vcpu = 1024 cpu units.

不用担心使用高CPU的应用程序，因为当达到90％时，您可以弹出一个新的1并对其进行负载均衡.那就是最经济有效的方式

and don't worry about application using high cpu because when it reaches 90 % you can popup a new 1 and load balanced it. thats the most cost effectively way
