Many thanks. Looks like it is the ghostscript version.
Did a test on Windows with pure gs 9.05, 9.10 and 9.15:
- 9.05 is extremely slow as I observed on Linux
- 9.10 and 9.15 are equaly fast like in your test.
The results are almost the same accross all the 3 gs-versions.
gs-call was:

Re: convert very slow for CMYK-PDFs
Thanks for the reply Fred.
I put 2 sample files here:
* http://148.251.8.102/RGB.pdf
* http://148.251.8.102/CMYK.pdf
My conversion times are 0.2s vs. 11s.
* convert RGB.pdf rgb.jpg (0.2s)
* convert CMYK.pdf cmyk.jpg (11s)
In the real application the conversion for CMYK is a bit more complex ...

convert very slow for CMYK-PDFs
Hello,
I encounter very slow PDF-conversions for CMYK-PDFs: 15 seconds for an example CMYK-PDF vs. 0.5 seconds when I manually convert the PDF to RGB before putting it into IM.
Is there any way to speed up the conversion for CMYK-PDFs? I believe it has to do with the options IM uses for the call ...
