-h, --help output usage information
For instance
# We can omit the protocol header if has omited, the protocol header will be `http://`
# 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`

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

Roadmap
- Better documentation
- i18n
- Increase the analysis statistics of resource items loaded on the page
- Statistical reports can be generated
- Data visualization
