Slow performance -annotate in ImageMagick 6.5.4-6

ImageMagick 6.5.4-6

Annotating an image is progressively slow by defining a longer text string. Is this a bug? I previously used version 6.3.5, however on a different server and did not encounter any performance problems with this function. With -drow text there are same performance problems. In the test link: http://www.jacobi-partner.de/test/index.php the command line is printed below the output image and convsion time...

Rebuild / reinstall ImageMagick and disable OpenMP:

• cd ImageMagick-6.5.4-9
  ./configure --disable-openmp
  make
  make install

Does that make a difference? We have found that certain versions of libgomp have a bug that slows ImageMagick down considerably.

This made a huge difference, thank you a lot. Also other funktions work now much faster...
