My testing gs v9.16 vs gs v8.17. A letter size PDF which contains a rectangle vignette 4" * 8.5" with Magenta 100% Yellow 80%. The following is the parameters, testing done on a Macbook Pro 2.3 Ghz i7 CPU with 8GB Ram.

$ gs -dSAFER -dBATCH -dNOPAUSE -r2400 -sDEVICE=tiffsep -sOutputFile=/Users/peter/Desktop/vignette-%03d.tif /Users/peter/Desktop/vignette.pdf

Time taken for gs 8.71 : 33 seconds
Time taken for gs 9.16 : 17 minutes 28 seconds

That's a huge difference ! 33 seconds vs 17 minutes 28 seconds. I wonder why version 9.16 can be so many times slower compare to the older version.

Is there any additional parameter for gs v9.16 to make it faster ?

It looks like a bug. If so where can I file it ?
