问题 I am attempting to write out an Excel file from an ASP.NET web server using OpenXML. I have about 2100 records and its taking around 20-30 seconds to do this. Any way I can make it faster?

Note: ExcelWriter is our custom class, but all its methods are directly from code in this link, http://msdn.microsoft.com/en-us/library/cc861607.aspx public static MemoryStream
