在开始一个新的小项目的玩耍的时候，发现有了这样一个不错的工具可以进行AB测试。

A/B测试是一种新兴的网页优化方法，可以用于增加转化率注册率等网页指标。AB测试本质上是个分离式组间实验，以前进行AB测试的技术成本和资源成本相对较高，但现在一系列专业的可视化实验工具的出现，AB测试已越来越成为网站优化常用的方法。

go boom安装

如果我们的go已经可以执行的话

go get github.com/rakyll/boom

然而，我没有设置GOPATH,于是提示了:

package github.com/rakyll/boom: cannot download, $GOPATH not set. For more details see: go help gopath

The Go path is used to resolve import statements.
It is implemented by and documented in the go/build package.

The GOPATH environment variable lists places to look for Go code.
On Unix, the value is a colon-separated string.
On Windows, the value is a semicolon-separated string.
On Plan 9, the value is a list.

GOPATH must be set to get, build and install packages outside the
standard Go tree.

接着

 export GOPATH="$HOME/gocode/"

go boom ab 测试

简单的示范如官方的代码所示:

 boom -n 1000 -c 100 http://0.0.0.0:8000/posts/1

用的是falcon + peewee + gunicorn搭建的简单server

看上去似乎还不错，只是是本地的。
