No, at least not for me.  I tested with some 750 pages PDF.

$ pdftocairo -png uml2.4.1-super-11-08-06.pdf page
# 345,99s user 1,16s system 99% cpu 5:50,00 total

$ gs -dSAFER -dNOPAUSE -sDEVICE=png16m -dTextAlphaBits=4 -dBATCH \
     -dQUIET -sOutputFile=page%d.png uml2.4.1-super-11-08-06.pdf
# 154,35s user 0,67s system 98% cpu 2:37,12 total

But what's really, really fast is the mudraw tool from the mupdf package

$ mudraw -o page%d.png uml2.4.1-super-11-08-06.pdf
# 24,19s user 1,36s system 97% cpu 26,156 total

doc-view uses that by default if it is installed.
