This article is to share with you about how to use the HTTP stress testing tool wrk. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Wrk is a simple HTTP stress testing tool, hosted on Github, https://github.com/wg/wrk.

A good feature of wrk is that it can squeeze a large amount of concurrency with a small number of threads.

Mac installation: brew install wrk

Parameter description:

-c,-- connections: total number of connections (connections per thread = total connections / threads)-d,-- duration: duration of the test, such as 2s (2second), 2m (2minute), 2h (hour)-t,-- threads: total number of threads that need to be executed-s,-- script: execute the Lua script, where the path and name of the lua script are written Later, we will give the case-H,-- header: the header information that needs to be added, pay attention to the syntax of header, for example,-H "token: abcdef", explain, token, colon, space, abcdefg (don't forget the space, otherwise you will report an error). -- latency: displays delay statistics-- timeout: timeout time

Execute demo: wrk-T1-d20s-c100 http://127.0.0.1:8080/outer/blackIpInfo description: use 1 thread, 100 connections to execute 20s

Execution result:

1 threads and 100 connections

Thread Stats Avg (average) Stdev (standard deviation) Max (maximum) + /-Stdev (proportion of plus or minus one standard deviation)

Latency (delay) 53.46ms 17.90ms 333.35ms 89.40%

Req/Sec (number of requests in processing) 1.88k 409.58 2.57k 69.02%

56190 requests in 30.05s, 20.84MB read

Requests/sec (average number of requests completed per second): 1869.61

Transfer/sec (average read data per second): 710.15KB
