🚀 A statistical analysis tool for performance testing


The name is short for Hi performance Or High performance


Hi guys, Please present your issue in English



npm install hiper -g

# or use yarn:
# yarn global add hiper

The output

Notice: It takes period (m)s to load .... the period means This test takes time. So -n go up and the period go up. not a bug




Key Value
DNS lookup time domainLookupEnd - domainLookupStart
TCP connect time connectEnd - connectStart
TTFB responseStart - requestStart
Download time of the page responseEnd - responseStart
After DOM Ready download time domComplete - domInteractive
White screen time domInteractive - navigationStart
DOM Ready time domContentLoadedEventEnd - navigationStart
Load time loadEventEnd - navigationStart



hiper --help

Usage: hiper [options] [url]

   -v, --version                output the version number
   -n, --count <n>              specified loading times (default: 20)
   -c, --config <path>          load the configuration file
   -u, --useragent <ua>         to set the useragent
   -H, --headless [b]           whether to use headless mode (default: true)
   -e, --executablePath <path>  use the specified chrome browser
   --no-cache                   disable cache (default: false)
   --no-javascript              disable javascript (default: false)
   --no-online                  disable network (defalut: false)
   -h, --help                   output usage information

For instance

 # We can omit the protocol header if has omitted, the protocol header will be `https://`

 # The simplest usage
 hiper baidu.com

 # if the url has any parameter, surround the url with double quotes
 hiper "baidu.com?a=1&b=2"

 #  Load the specified page 100 times
 hiper -n 100 "baidu.com?a=1&b=2"

 #  Load the specified page 100 times without `cache`
 hiper -n 100 "baidu.com?a=1&b=2" --no-cache

 #  Load the specified page 100 times without `javascript`
 hiper -n 100 "baidu.com?a=1&b=2" --no-javascript
 #  Load the specified page 100 times with `headless = false`
 hiper -n 100 "baidu.com?a=1&b=2" -H false

 #  Load the specified page 100 times with set `useragent`
 hiper -n 100 "baidu.com?a=1&b=2" -u "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36"


Support .json and .js config

  1. json
   // options Pointing to a specific chrome executable, this configuration is generally not required unless you want to test a specific version of chrome
   "executablePath": "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
   // required The url you want to test
   "url": "https://example.com",
   // options Cookies required for this test. It's usually a cookie for login information Array | Object
   "cookies": [{
      "name": "token",
      "value": "9+cL224Xh6VuRT",
      "domain": "example.com",
      "path": "/",
      "size": 294,
      "httpOnly": true
   // options default: 20 Test times
   "count": 100,
   // options default: true Whether to use headless mode 
   "headless": true,
   // options default: false Disable cache 
   "noCache": false,
   // options default: false Disable javascript
   "noJavascript": false,
   // options default: false Disable network
   "noOnline": false,
   // options Set the useragent information
   "useragent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36",
   // options Set the viewport information
   "viewport": {
      // options
      "width": 375,
      // options
      "height": 812,
      // options default: 1 devicePixelRatio
      "deviceScaleFactor": 3,
      // options default: false Whether to simulate mobile
      "isMobile": false,
      // options default: false Whether touch events are supported
      "hasTouch": false,
      // options default: false Is it horizontal or not
      "isLandscape": false
  1. js

Having a JS file for config allows people to use ENV variables. For example, let's say I want to test the site on an authenticated state. I can pass some cookie that is used to identify me through ENV variables and having a JS based config file makes this simple. For example

module.exports = {
    cookies:  [{
        name: 'token',
        value: process.env.authtoken,
        domain: 'example.com',
        path: '/',
        httpOnly: true
# Load the above configuration file (Let's say this file is under /home/)
hiper -c /home/config.json

# Or you can also use JS files for configuration
hiper -c /home/config.js

Pain point

After we have developed a project or optimized the performance of a project,

how do we measure the performance of this project?

A common approach is to look at the data in the performance and network in the Dev Tool, record a few key performance metrics, and refresh them a few times before looking at those performance metrics,

Sometimes we find that due to the small sample size, the current Network/CPU/Memory load is heavily impacted, and sometimes the optimized project is slower than before the optimization.

If there is a tool, request web page many times, and then taking out the various performance indicators averaging, we can very accurately know the optimization is positive or negative.

In addition, you can also make a comparison and get accurate data about how much you have optimized. This tool is designed to solve the pain point.

At the same time, this tool is also a good tool for us to learn about the "browser's process of load and rendering" and "performance optimization", so that we don't get wrong conclusions when there are too few samples


  1. Better documentation
  2. i18n
  3. Increase the analysis statistics of resource items loaded on the page
  4. Statistical reports can be generated
  5. Data visualization


  1. Fork it
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Add some feature')
  4. Push to the branch (git push origin my-new-feature)
  5. Create new Pull Request
