Blow is a HTTP(S) benchmarking tool, written in Golang. It uses excellent fasthttp instead of Go's default net/http due to its lightning fast performance.
Features:
- support profile like hurl format at 2021-11-25.
- 创建示例 profile 文件：
blow --profile p1.http:new - 运行 profile 文件所有请求1次
blow --profile p1.http -n1 - 运行 profile 文件tag=6的请求1次
blow --profile p1.http:6 -n1 - 运行 profile 文件tag=从4到6的请求1次
blow --profile p1.http:4-6 -n1 - 运行 profile 文件tag=1，或者从4到6的请求1次
blow --profile p1.http:1,4-6 -n1
- 创建示例 profile 文件：
- test with detail request and response printing by
-n1 - enable web service by
-v - enable logging for requests and responses details by
-vv - status by response json fields instead of http status code. e.g.
blow :9335 --status status. - network simulating. e.g.
blow :9335 --network 200Kto simulating bandwidth 200KB/s without latency. - network simulating. e.g.
blow :9335 --network 20M:500msto simulating bandwidth 20M/s and latency 500ms. - uploading files in a dir. e.g.
blow :9335 --upload image-dir -n1 - uploading single file. e.g.
blow :9335 --upload 1.jpg -n1 - uploading big files without cache. e.g.
blow :9335 --upload .:nocache --user scott:tiger -n1 - basic auth. e.g.
blow :9335 --user username:password - thinking time among requests. e.g.
blow :8080 --think 100ms,blow :8080 --think 100-300ms - QPS to limit requests per second and per worker. e.g.
blow :8080 --qps 1000 - help
blow --help
Blow runs at a specified connections(option -c) concurrently and real-time records a summary statistics, histogram
of execution time and calculates percentiles to display on Web UI and terminal. It can run for a set duration(
option -d), for a fixed number of requests(option -n), or until Ctrl-C interrupted.
The implementation of real-time computing Histograms and Quantiles using stream-based algorithms inspired by prometheus with low memory and CPU bounds. so it's almost no additional performance overhead for benchmarking.
