性能测试工具 boom
Boom 是 google 一女工程师使用 Go 语言开发的类似 apache ab 的性能测试工具。相比 ab，boom跨平台性更好，而且更容易安装。
##安装##
`go get github.com/rakyll/boom`
##使用##
```
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.
-t Timeout in ms.
-A HTTP Accept header.
-d HTTP request body.
-T Content-type, defaults to "text/html".
-a Basic authentication, username:password.
-x HTTP Proxy address as host:port.
-allow-insecure Allow bad/expired TLS/SSL certificates.
-disable-compression Disable compression.
-disable-keepalive Disable keep-alive, prevents re-use of TCP
connections between different HTTP requests.
-cpus Number of used cpu cores.
(default for current machine is 1 cores)
