web缓存服务器性能比较 nuster vs nginx vs varnish测试环境系统参数配置文件检查http头大小Benchmark结果Raw output

简单比较了web缓存服务器 nuster, nginx和varnish的缓存性能，结果显示nuster的RPS（每秒请求数）单进程模式下大概是nginx的3倍，多进程下是nginx的2倍，varnish的3倍。

<code>/helloworld</code> url包含 <code>hello world</code>文字的结果.

两台linux服务器, server129装有origin web server,

cache服务器nuster/nginx/varnish 装在 server130.

origin web server: set <code>server_tokens off;</code> to make http header <code>server</code> same.

Intel(R) Xeon(R) CPU X5650 @ 2.67GHz(12 cores)

RAM 32GB

1Gbps ethernet card

CentOS: 7.4.1708 (Core)

wrk: 4.0.2-2-g91655b5

varnish: (varnish-4.1.8 revision d266ac5c6)

nginx: nginx/1.12.2

nuster: nuster/1.7.9.1

所有http头都是一样的

Note that HAProxy removes <code>Connection: Keep-Alive</code> header when its <code>HTTP/1.1</code>

while nginx/varnish do not, so I added <code>Connectio1: keep-aliv1</code> to make the size same.

See nuster config file above

没有用满所有带宽

nuster 差不多是 nginx的3倍

12 cores

没沾满前nuster是nginx的2倍，varnish的3倍

沾满时基本差不多

I did the test again with <code>wrk</code> on server130 using 127.0.0.1 since I do not have a 10Gbps network

nuster is almost 2 times faster than nginx and varnish

error occurs with nginx-1core when the connections is 5000
