snaic和tornado的简单性能测试

时间：2024-01-25 18:45:08

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

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。
