Our browser made a total of 106 requests to load all elements on the main page. We found that 95% of them (101 requests) were addressed to the original, 2% (2 requests) were made to and 2% (2 requests) were made to The less responsive or slowest element that took the longest time to load (4.2 sec) belongs to the original domain

Additional info on


The browser has sent 104 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Xbit. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 6 to 1 for JavaScripts and from 6 to 1 for CSS and as a result speed up the page load time.









Possible request optimization











Normal result


As for redirects, our browser was forwarded to before it reached this domain.

IP address uses IP address which is currently shared with 4 other domains. 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.

Our service has detected that Japanese is used on the page, and it matches the claimed language. Our system also found out that 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.
