How will TagMan effect page download speeds?
TagMan consists of a Javascript library and short amount of code that is included in each page. The library is standardised and shared across all clients so that users only download it once per session. When the page is loaded an initial call to TagMan retrieves the parameter requirements and then TagMan waits for the page to complete before continuing. Unless they need to be run directly into the page, tags are usually written out into an Iframe, along with the flash pixel. The advantage of writing tags out into an Iframe is they will not delay the page from completing. If the business logic dictates that no 3rd party tags need to be served, minimal code is sent back to the page, keeping bandwidth to an absolute minimum and reducing the impact on page download speed.
