Our browser made a total of 172 requests to load all elements on the main page. We found that 1% of them (1 request) were addressed to the original Photondelta.eu, 99% (171 requests) were made to Photondelta.com. The less responsive or slowest element that took the longest time to load (1.1 sec) relates to the external source Photondelta.com.
Page size can be reduced by 416.4 kB (4%)
9.4 MB
8.9 MB
In fact, the total size of Photondelta.eu main page is 9.4 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. 80% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Images take 8.9 MB which makes up the majority of the site volume.
Potential reduce by 416.3 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 416.3 kB or 86% of the original size.
Potential reduce by 0 B
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. Photon Delta images are well optimized though.
Potential reduce by 55 B
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. This website has mostly compressed JavaScripts.
Number of requests can be reduced by 9 (5%)
169
160
The browser has sent 169 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Photon Delta. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests and as a result speed up the page load time.
