Continued Problem with PDF file size

I am still experiancing a problem with PDF file size. the PDF files many times are larger than the DWG they were made from. 

original file size of 291K. DS PDF is 753K. Cute PDF is 225K. AC PDF is 135K. Open the file using e-Drawings and then print to PDF is 158K. Export PDF results in a 559K file size.

 

I am useing the default  .SKX Font.

This is not the first complaint about this and the only answer is to use cutePDF which is not solveing the problem. What do I need to do to FIX this?
