Re: CPU Usage (again)

Thank you for the fast reply. I'll give that a try ad report back. I'm just using the default yum binaries currently.

CPU Usage (again)

We recently upgraded our cluster to centos 6, and seem to be having cpu usage problems with imagemagick once again. I have edited the policy.xml and changed threads to 1. I verified with convert -list resource that "Thread" is showing 1, yet each convert process is taking up to 900% of our cpu, or 9 ...

Imagick and threads

First some background. We resize about 50 million source images into 5 different sizes. For this we use a cluster of 16 dual 8 core servers. We don't have imagemagick installed on any of the servers, but rather just imagick through the yum pecl package (yum install php-pecl-imagick). This works fine ...
