Only in some cases. Also it increases latency. Here’s my old article about Microsoft’s binary XML format: http://const.me/articles/net-tcp/ http://const.me/articles/net-tcp/ As you see, for some payloads it compresses XML to 9% of the original size. The data contract serializer included in .NET framework (and even in .NET Core) can read & write objects directly from/to this binary serialization format, without intermediate text XML anywhere.
