Converting the attached PDF file to png with GS takes 40 seconds and converting the same file with pdfdraw takes 126 seconds. I can reproduce this behaviour with other PDF files too.

Here is the command line i use with Ghostscript:
gswin32c -r200x200 -dNOPAUSE -dBATCH -sDEVICE=png16m -sOutputFile=t%%d.png -f test.pdf

Here is the pdfdraw command line:
pdfdraw.exe -r 200 -o out%%d.png test.pdf

I'm not seeing the difference. On my machine, pdfdraw takes 22s user time. Ghostscript takes 40s user time, even without anti-aliasing.
