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
You are correct. It is Q16 version. I'll recompile and test again! Thanks!

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 . . .

Hello list,

Im running debian and until recently I used their ImageMagick package with version 6.2.4.

Using this package I converted a 8 MB psd file to png in 3 seconds.

Now I downloaded and compiled the latest source 6.3.5 code.

Using the same convert command on the same file takes 17 seconds(!)

Has anyone the slightest idea what could be wrong and what configure flags that could have this much impact.

The systems is a Intel P4 2.8GHz, with 1GB ram running debian etch.

Thanks,
Henrik
