3D VR: http://www.cmse.gov.cn/vr/vr/index.html?scene_id=55299440

Just run the author's benchmark program on my i5-9600k:

    |          | i5-9600k     | i7-7700HQ | Apple M1  |  
    |strtod    | 217.97 MB/s  | 80 MB/s   | 115 MB/s  |

    |fastfloat | 1400.15 MB/s | 1000 MB/s | 1800 MB/s |

It's font ligatures, it can be enabled by setting CSS `font-variant-ligatures` property with some fonts, such as "Fira Code" font.

Only TCP port 80 and 443 requires ICP.

My experience is that if there is a VPS located in the U.S., which only has a static page/file, and there is no CDN, whether it is access from Japan, Hong Kong, Singapore, or from mainland China, the speed is similar. Access from mainland China will not be significantly slower. I did this test over and over again.

The reason your site 'slows down' may be that your site is blocked, or the embedded Javascript (such as Google Analytics, Adsense, DISQUS) or CSS/Web Font (such as Google fonts) has listed on GFW's blacklist. I feel sorry that my last reply may be not made it clear, I mean that the point of this project is not all the truth (why your site is slow), or even a little misleading. Since running website for several years, I must be honest point out that if the mainland China market make sense to you and you want to keep your website always smooth, the only way is to place the server in mainland China or Japan, all other testing, optimization is a waste of time and money.

It is also very interesting to have such a service provided by a Chinese developer (the author)

Yes, this project is misleading, in fact, in mainland China to visit foreign websites is not slow, there are only two cases, blocked or not blocked, the former simply can not open, the latter fast enough. There are many surfers in mainland China who buy VPN servers located in such as the US and then have quick access to the blocked websites, indicating that the lines are fast enough. If your site is embedded with a JavaScript code come from the blocked website (a limited number, such as Facebook, Google), it will also cause your page can not to load, just remove the js code and nothing else is wrong. It is not recommended to be misled by this site.

Spring Framework

1. Elegant structure 2. Strict code style 3. Project size is not too large 4. Have detailed documentation

In fact Netbeans is very good at JavaScript and web page edit, it has the most intelligent autocomplete and refactoring I ever seen, it is also free and open source.

In some special environment, such as Electron (Atom shell), that can ignore the cross-browser problem, writing application using native Web API and DOM API and ES6 is elegant and effective.
