Nginx/Unit vs Gunicorn 的效能與消耗資源測試
Nginx/Unit vs Gunicorn 的Apache(ab)效能與消耗資源測試
tags: Ngix unit gunicorn ab wrt
我開了一個1 core，記憶體只有256mb的 lxc (openVZ) 做為測試平台。先說結論，unit的速度較gunicorn快一些， 使用記憶體也差不多，但對於使用cpu就差非常多了，unit只用了gunicorn的2/5的算力。
一支程式 使用 unit做為微伺服器，以 apache/ab 作壓力測試

消耗資源比較
unit 勝
gunicorn 敗
Nginx/Unit vs Gunicorn 的wrt效能與消耗資源測試
wrk 是用C語言寫的http benchmark 工具，是一種簡易的HTTP 性能測試。
- 安裝 wrt
作者將原始檔放在git上，所以要安裝它最直接的方法
就是去git抓下來make就可以了!以下是指令
yum groupinstall 'Development Tools'
yum -y install openssl-devel git
git clone https://github.com/wg/wrk.git wrk
cd wrk
make
\# copy wrk 到 PATH 可執行的目錄中，我的習慣釋放到/usr/local/bin
cp wrk /usr/local/bin
- 使用方法
Usage: wrk <options> <url>
Options:
-c, --connections <N> Connections to keep open
-d, --duration <T> Duration of test
-t, --threads <N> Number of threads to use
-s, --script <S> Load Lua script file
-H, --header <H> Add header to request
--latency Print latency statistics
--timeout <T> Socket/request timeout
-v, --version Print version details
Numeric arguments may include a SI unit (1k, 1M, 1G)
Time arguments may include a time unit (2s, 2m, 2h)
例如: wrk -t12 -c400 -d30s http://127.0.0.1:8300/
輸出 (output)
Running 30s test @ http://127.0.0.1:8300/
12 threads and 400 connections
Thread Stats Avg Stdev Max +/- Stdev
Latency 244.87ms 16.11ms 400.26ms 93.68%
Req/Sec 137.86 93.22 333.00 59.80%
48060 requests in 30.06s, 3.55GB read
Requests/sec: 1598.63
Transfer/sec: 121.00MB
-t12 用 12 個線程 # -c400 模擬 400 個併發連接 # -d30s 持續 30 秒
Unit Server
wrk -t12 -c400 -d30s http://XXXX
Running 30s test @ http://XXXX
12 threads and 400 connections
Thread Stats Avg Stdev Max +/- Stdev

Transfer/sec: 1.90MB
Gunicorn Server
wrk -t12 -c400 -d30s http://XXXX
Running 30s test @ http://XXXX
12 threads and 400 connections
Thread Stats Avg Stdev Max +/- Stdev
Latency 132.75ms 170.39ms 1.95s 90.85%
Req/Sec 157.16 85.44 666.00 67.08%
49022 requests in 30.06s, 11.08MB read
Socket errors: connect 0, read 0, write 0, timeout 24
Requests/sec: 1630.85
Transfer/sec: 377.45KB
結論:unit完勝，速度約為gunicorn的5倍!!!
調整參數進行第二次測試
Unit:
wrk -t12 -c600 -d60s http://xxxxxx:2101/
Running 1m test @ http://xxxxxx:2101/

Gunicorn:
wrk -t12 -c600 -d60s http://xxxxxx:2110/
