Description Marcos H. Woehrmann 2011-03-11 16:35:11 UTC 
The customer reports and I've verified Ghostscript 9.01 takes a very long to render the attached file at 600 dpi.  In addition Ghostscript generates a >4 gig temporary file.

The command line I'm using for testing:

  bin/gs -sDEVICE=ppmraw -o test.ppm -r600 ./45513.pdf
Comment 2 Marcos H. Woehrmann 2011-03-17 17:21:52 UTC 
I tried comparing our processing time/memory usage to Acrobat but the largest size that I can get Acrobat to export the test file to a TIFF is at 150 dpi, so I'm comparing those times:

Acrobat 10.0.1 ~36 seconds and max memory usage 140 MB

Ghostscript r12300 with default options ~60 seconds and 35 MB

Ghostscript r12300 with -dMaxBitmap=1500000000 ~25 seconds and 910 MB
