Re: ImageMagick 6.3.5 compile flags big performance drop

Hi Henrik!

It coud be that you compare a 8bit and a 16bit Version from ImageMagick.

type on the shell:
identify -version
Version: ImageMagick 6.2.8 11/16/06 Q8 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2006 ImageMagick Studio LLC

Q8 = 8bit and Q16=16bit Version

I recomend compiling IM from the sources and use this option while  
configure: --with-quantum-depth=8
This improves speed drastically and I think 8bit depth is enough for  
daily work . . .
