I have huge troubles running my cakephp application now.
after upgrading vom lenny to squeeze (even tried a complete reinstall of sqeeze) imagick is so incredible slow that it simply shuts down my server.
I have several image galleries which use imagick to create thumbs.
50 images needed less then 30 seconds (2000×1200 pixel) on lenny. NOW it needs more than an hour..
Processor is at 100% for the complete time making other processes like apache very slow.
is this a known bug in squeeze?
it is making me crazy!
I even tried to run the application of other servers. a friend gave me access to his archlinux + nginx. fast as a rocket (less then 23 seconds).
it is definitly a sqeeze problem.
i simply installed it via “apt-get install imagemagick”
and added the php extension “php-imagick”
details:
Version: ImageMagick 6.6.0-4 2010-11-16 Q16
One solution seems to be to downgrade imagemagick:

There’s a debian bug (#638409) opened about this, seems to be caused by imagemagick’s use of openmp:

Since we have this problem ourselves, we will be trying both solutions shortly 🙂
