Using pdfinfo from xpdf shows for ESP ghostscript for one page of the
example PostScript:

 pdfinfo ~/x.pdf 
 Producer:       ESP Ghostscript 8.15
 CreationDate:   Tue Jul  7 12:30:57 2009
 ModDate:        Tue Jul  7 12:30:57 2009
 Tagged:         no
 Pages:          1
 Encrypted:      no
 Page size:      595 x 842 pts (A4)
 File size:      11117 bytes
 Optimized:      no
 PDF version:    1.3

and for GPL ghostscript 8.64:

 pdfinfo ~/y.pdf
 Title:          step1
 Author:         Adam Tauno Williams
 Creator:        a2ps version 4.13
 Producer:       GPL Ghostscript 8.64
 CreationDate:   Tue Jul  7 10:32:36 2009
 ModDate:        Tue Jul  7 10:32:36 2009
 Tagged:         no
 Pages:          1
 Encrypted:      no
 Page size:      595 x 842 pts (A4)
 File size:      3063903 bytes
 Optimized:      no
 PDF version:    1.4

the file differ by a factor 275 in size.  Some of the speed
difference seems to be caused by increased I/O load IMHO.
