前言:
国人开源的一款开源的基于golang的命令行压测工具,这里记录一下,以后可能会用得到。
特点:
- 跨平台,无运行时依赖(基于 golang )
- 高性能,比常见的 hey,ab,siege 等性能高不少(基本和 wrk 持平)
- 终端实时展示性能数据,包括 RPS,延迟统计,百分位,Histogram 分布等
- 支持实时网页展示,更全方面展示各时间点的压测数据
演示:
❯ ./plow http://127.0.0.1:8080/hello -c 20
Benchmarking http://127.0.0.1:8080/hello using 20 connection(s).
> Real-time charts is listening on http://127.0.0.1:18888/
