How much will Fast Infoset reduce the size of my documents?
You can use the freely available FI Converter to find out. It will convert your text-encoded documents to Fast Infoset-encoded documents and report the conversion ratios. If you also wish to convert your text-encoded documents to .NET Binary-encoded documents so that you can compare the conversion ratios of .NET Binary to those of Fast Infoset, use the MSBXML Converter.
