Is XmlTextWriter the fastest way to write out an XML file?

Hi all;

At present I am using XmlTextWriter with WrieStartElement(), WriteAttributeString(), & WriteEndElement(). Is this the fastest way to create an XML file?

This is for a programming writing the sheet.xml for an xlsx file where the spreadsheet has a million rows - so the speed of creating the XML has a giant impact.

thanks - dave
