snaic和tornado的简单性能测试
操作系统 : centos7.3.1611_x64
python 版本 : 3.6.8
tornado版本:6.0.2
snaic版本:19.9.0
cpu : intel(r) core(tm) i5-2320 cpu @ 3.00ghz 4核
之前一直使用tornado作为http相关python程序的框架,最近查资料发现新出的snaic性能很高,这里在同样硬件条件下使用ab进行简单的压测。
准备工作
安装apache ab工具:
yum -y install httpd-tools
压测命令:
ab -c 30 -n 100000 http://127.0.0.1:9093/
参数说明:
-c :模拟并发数
-n : 总请求数
对比测试

tornado测试结果:

snaic测试结果:
server software: server hostname: 127.0.0.1 server port: 9093 document path: / document length: 12 bytes concurrency level: 30 time taken for tests: 20.164 seconds complete requests: 100000 failed requests: 0 write errors: 0 total transferred: 11100000 bytes html transferred: 1200000 bytes requests per second: 4959.29 [#/sec] (mean) time per request: 6.049 [ms] (mean) time per request: 0.202 [ms] (mean, across all concurrent requests) transfer rate: 537.58 [kbytes/sec] received connection times (ms) min mean[+/-sd] median max connect: 0 2 0.5 2 11 processing: 1 4 1.5 4 38 waiting: 0 4 1.4 3 37 total: 1 6 1.5 6 41 percentage of the requests served within a certain time (ms) 50% 6 66% 6 75% 7 80% 7 90% 7 95% 8 98% 9 99% 10 100% 41 (longest request)
从测试结果可以看到,开启两个进程情况下:
tornado的cps是 1215.33 ,平均响应时间是 24.685 ms
snaic的cps是 4959.29 ,平均响应时间是 6.049 ms
修改并发数后的测试数据如下:
测试结果对比如下:
从测试数据来看,snaic的cps比tornado高,平均响应时间方面,snaic也比tornado短。
