Text values of attributes and elements are stored with length prefixes rather than end delimiters, and data segments do not require escapement for special characters.
Fast Infoset is a higher level format built on ASN.1 forms and notation.
Element and attribute names are stored within the octet stream, unlike traditional ASN.1 encoding schemes.
An index table is built for most strings, which includes element and attribute names, and their values.

Fast Infoset uses less bandwidth than XML and is faster to process, making it a superior choice.
Passing XML through the Internet – When an application passes data over the internet, network bandwidth can be a major bottleneck, seriously degrading the performance of client applications and limiting the server's power to process requests.
