🚀 A statistical analysis tool for performance testing
The name is short forHiperformanceOrHighperformance
Hi guys, Please present your issue in English
请使用英语提issue
npm install hiper -g# or use yarn:# yarn global add hiper
Notice:It takes period (m)s to load .... theperiod meansThis 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 |

- 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 configurationhiper -c /home/config.js
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 theperformance andnetwork in theDev 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 currentNetwork/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 canvery accurately know the optimization is positive or negative.
In addition, you can also make a comparison and getaccurate data abouthow 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
