wrk - a HTTP benchmarking tool
|
|
|
|
wrk is a modern HTTP benchmarking tool capable of generating significant
|
|
load when run on a single multi-core CPU. It combines a multithreaded
|
|
design with scalable event notification systems such as epoll and kqueue.
|
|
|
|
An optional LuaJIT script can perform HTTP request generation, response
|
|
processing, and custom reporting. Details are available in SCRIPTING and
|
|
several examples are located in scripts/
|
|
|
|
Basic Usage
|
|
|
|
wrk -t12 -c400 -d30s http://127.0.0.1:8080/index.html
|
|
|
|
This runs a benchmark for 30 seconds, using 12 threads, and keeping
|
|
400 HTTP connections open.
|
|
|
|
Output:
|
|
|
|
Running 30s test @ http://127.0.0.1:8080/index.html
|
|
12 threads and 400 connections

Benchmarking Tips
|
|
|
|
The machine running wrk must have a sufficient number of ephemeral ports
|
|
available and closed sockets should be recycled quickly. To handle the
|
|
initial connection burst the server's listen(2) backlog should be greater
|
|
than the number of concurrent connections being tested.
|
|
|
|
A user script that only changes the HTTP method, path, adds headers or
|
|
a body, will have no performance impact. Per-request actions, particularly
|
|
building a new HTTP request, and use of response() will necessarily reduce
|
|
the amount of load that can be generated.
