I noticed that the OCR process itself does not seem to be so CPU consuming, but imagemagick was often consuming resources (which I replaced now). Anyway, sure it adds some overhead, but if you take into account that the whole test only even starts when an image is found, then this doesn't seem too bad to me. Not every mail I get contains an image, lets say every tenth maybe. That is acceptable for me at least.
