Click here to check amazing Arduino JSON content for Poland. Otherwise, check out these important facts you probably never knew about arduinojson.org
ArduinoJson is a JSON library for Arduino, IoT, and any embedded C++ project. It supports JSON serialization, JSON deserialization, MessagePack, streams, and fixed memory allocation. It has a simple A...
Visit arduinojson.orgWe analyzed Arduinojson.org page load time and found that the first response time was 83 ms and then it took 4.9 sec to load all DOM resources and completely render a web page. This is a poor result, as 70% of websites can load faster.

Our browser made a total of 94 requests to load all elements on the main page. We found that 53% of them (50 requests) were addressed to the original Arduinojson.org, 10% (9 requests) were made to Avatars0.githubusercontent.com and 6% (6 requests) were made to Youtube.com. The less responsive or slowest element that took the longest time to load (672 ms) belongs to the original domain Arduinojson.org.
Page size can be reduced by 563.6 kB (23%)
2.4 MB
1.8 MB
In fact, the total size of Arduinojson.org main page is 2.4 MB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 60% of websites need less resources to load. Images take 1.8 MB which makes up the majority of the site volume.
Potential reduce by 87.3 kB
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 87.3 kB or 77% of the original size.
Potential reduce by 139.9 kB
Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. Arduino JSON images are well optimized though.
Potential reduce by 24.4 kB
It’s better to minify JavaScript in order to improve website performance. The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 24.4 kB or 34% of the original size.
Potential reduce by 312.1 kB
CSS files minification is very important to reduce a web page rendering time. The faster CSS files can load, the earlier a page can be rendered. Arduinojson.org needs all CSS files to be minified and compressed as it can save up to 312.1 kB or 85% of the original size.
Number of requests can be reduced by 11 (12%)
91
80
The browser has sent 91 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Arduino JSON. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 12 to 1 for JavaScripts and as a result speed up the page load time.
