So, as you guessed, j1 took just under 10 minutes whereas j8 took under 2. Which is what I would expect. Okay, thanks for the help. It's time I go beat up our vendor now. As far as understand their explanation is that they simply call the thumbnail creation routine sequentially, one image at a time, which in turn goes to PHP which then goes to Apache. And as far as the OS is concerned, it received 1 single call from Apache to do something, as opposed to multiple calls at the same time.

Would that be a reasonable explanation (of why their process takes so long)? Because they're not spawning multiple calls ... ?
