In fact, the total size of H5dev.cn main page is 15.3 kB. This result falls within a vast category (top 1 000 000) of heavyweight, probably not optimized, and thus slow loading web pages. Only a small number of websites need less resources to load. HTML takes 15.3 kB which makes up the majority of the site volume.
Original 15.3 kB
After minification 15.2 kB
After compression 772 B
HTML content can be minified and compressed by a website’s server. The most efficient way is to compress content using GZIP which reduces data amount travelling through the network between server and browser. HTML code on this page is well minified. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 14.5 kB or 95% of the original size.

Possible request optimization
As for redirects, our browser reached this domain in two steps. The first redirect led to https://gitlab.yunkongtech.com:443/, then it was forwarded to https://gitlab.yunkongtech.com/users/sign_in, and finally we managed to open this domain. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.
H5dev.cn uses IP address which is currently shared with 1 other domain. The more sites share the same IP address, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.
Language and encoding
Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise H5dev.cn can be misinterpreted by Google and other search engines. Our service has detected that Chinese is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that H5dev.cn main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.
H5dev.cn has no SSL certificate. Web browsing can be safer with HTTPS connection, so we suggest that it should be obtained for this site.
Visitor World Map
The server of H5dev.cn is located in China, but, unfortunately, we cannot identify the countries where the visitors come from and thus it’s impossible to define if the distance can potentially affect the page load time.
Social Sharing Optimization
Open Graph description is not detected on the main page of H 5 Dev. Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
