Boom — Go语言实现的性能测试工具 HTTP(S) load generator, ApacheBench (ab) replacement, written in Go Boom is a tiny program that sends some load to a web application. It's similar to Apache Bench (ab), but with better availability across different platforms and a less troubling installation experience. 项目地址：[https://github.com/rakyll/boom](https://github.com/rakyll/boom) 安装：go get github.com/rakyll/boom **Usage** Usage: boom [options...] <url> Options: -n Number of requests to run. -c Number of requests to run concurrently. Total number of requests cannot be smaller than the concurency level. -q Rate limit, in seconds (QPS). -o Output type. If none provided, a summary is printed. "csv" is the only supported alternative. Dumps the response metrics in comma-seperated values format. -m HTTP method, one of GET, POST, PUT, DELETE, HEAD, OPTIONS. -h Custom HTTP headers, name1:value1;name2:value2. -d HTTP request body. -T Content-type, defaults to "text/html". -a Basic authentication, username:password. -allow-insecure Allow bad/expired TLS/SSL certificates. **输出示例：** % boom -n 1000 -c 100 https://google.com 1000 / 1000 ∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎∎ 100.00 % Summary: Total: 21.1307 secs.
