I'm running on Axivo MariaDB 5.2.10 and PHP 5.3.10 performance RPM's.
What I noticed rightaway is that the import of attachments uses only one worker:
That is because there is only one request sent at the time... but look at the huge CPU usage. Usually the load is distributed gradually through all workers, which makes this step a real performance issue. I'm not worried about the PHP size limitations or the number of open files, sysctl and other env settings are adjusted properly with plenty of room to spare for top performance. Any idea what can cause the random import failure? Is there a way I can run the import through console?
I'm looking at 150GB worth of attachments... this looks like is going to be a very long import.
Thanks for your help.
