We found that 93% of them (123 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 (4.6 sec) belongs to the original domain

Additional info on


The browser has sent 131 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Sumo. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 10 to 1 for JavaScripts and from 5 to 1 for CSS and as a result speed up the page load time.











Possible request optimization













Normal result

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.
