- http://tag1consulting.com/files/PageLoad.pdf One pages on which there will always be a lot of objects, you can sometimes see a performance gain by serving the content from multiple domains. (For example, server1.sample.com, server2.sample.com, server3.sample.com, even if all are served from the same physical server with the same IP address). Web browsers limit the number of active connections allowed from a single domain, thus by serving content from multiple domains you can cause web browsers to download more objects on a given page at the same time. Note that on the first visit to your page, the client web browser has to do a DNS lookup for each domain that you use, so serving objects from too many domains can actually cause a slowdown. It is generally recommended to use anywhere from two to four domains, depending on how many objects you are serving per page. (Tag1 Consulting)
