The update to active.com last week brought with it a significant improvement in load time and page size. We met last month to determine how we could give the site a bit more zip and came up with a solid list of about 8 items. One of those items, removal of VIEWSTATE, was included in our latest update. VIEWSTATE is a variable used in ASP.NET to make HTTP, a stateless protocol, act like a stateful one. Most of the pages on active.com, however, dont require state, making VIEWSTATE extraneous. And on average VIEWSTATE added an additional 50 to 150 KB to page sizes to the site.
In our latest release we turned VIEWSTATE off. Data shows us that the site is about 23% faster and, with an average page size reduction of 27%, well lower consumed bandwidth out of our production data center by about 500 to 800 GB/month.
