I currently have an 8-core web server that is running into load problems due to heavy amounts of image processing--Imagemagick and other associated software will often spike the server's load up to 50+.

My thought would be to isolate Imagemagick onto one or two cores and then let all other processes distribute themselves on all other cores. Is there a way to set a core to exclusively work certain jobs with taskset AND ensure that no other tasks are assigned to that core? Is this something better handled by numactl?

    What are the actual effects of the 50+ load? Have you used nice to decrease priority of the heavy image processing?

  • +1 for nice. You could create an alias for whichever imagemagick command is being run which uses nice.
