Upload 2GB file to Azure blob -

I have a zipped 2GB file that I want to upload to Windows Blue via my home cable connection, how long I am Should expect this file to be uploaded? Does anyone average my upload time for their files?

Also, when I create a Blob to upload a file

  CloudBlob _blob = _container.GetBlobReference ("file1");   
 Is it making  CloudBlockBlob  or  CloudPageBlob  by default? I am using the code above to upload files and it is quite slow.   
 
 
  cloudblock _blob = _container.getBlobReference ("file1");   
 It does not make CloudBlockBlob or CloudPageBlob by default.  
 If you want to use CloudBlockBlob (Azure SDK v2.0):  
  // "Blobb to retrieve the context blob called" Claudblokblob blob = container Gateblocksblockback ("blobb");   
 Now divide your file into smaller pieces (4 MB max), and upload each piece like this:  
  blob.PutBlock (blockId , MemoryStream, null);   
 Where:  Block Id  is a base 64-encoded block ID that recognizes the block.  
 and  memory stream  A stream that provides data for blocks.
