Hmmm. There's some measure of apples to crankcases in this comparison, but here's a run on my 2.8 GHz P4 (not Core or later) running Linux: $ ls -l *.pdf -rw-rw-r-- 1 dnl dnl 354390 2008-05-07 17:34 ENC-M200-LCD-manual.pdf $ time convert -compress Group4 -density 200 -monochrome \ ENC-M200-LCD-manual.pdf x.tif real 0m27.371s user 0m25.146s sys 0m1.224s $ So, 27 seconds elapsed time v. your 3 minutes. What does your system look like? What CPU do you have? How much memory is on your system? What else is running? Are you paging? What does your disk system look like? -- David N.
