When the Lytics tag loads for the first time several requests are made. There are two libraries being loaded, one is for tracking and the other is for personalization. There are a couple calls for each sending data back to Lytics for tracking and to check for active personalize campaigns. All are OK and required for functionality and after the initial load where the js/css is loaded, the number of calls will drop.
Additionally, all the calls are asynchronous and will not affect your site performance.
