Hi everyone,

How can I adjust MAGICK_THREAD_LIMIT, I know I ahve to add a line to configure.xml:

<configure name="MAGICK_THREAD_LIMIT" value="4"/>

But after that, do I have to recompile imagemagick or restart something?

I am using ImageMagick 6.3.7

Thanks

The MAGICK_THREAD_LIMIT variable limits the number of threads if ImageMagick is build with OpenMP enabled. Check your version of ImageMagick:

• convert -version

If OpenMP is enabled you'll get something like

• Version: ImageMagick 6.4.8-10 2009-01-26 Q16 OpenMP http://www.imagemagick.org

By default the number of threads is equal to the number of cores of your system (dual core means 2 threads).
