Mac OS X - Opening Project Crawls - Uses Only 1/2 Core on a 12 Core Mac Pro

Feb 1, 2012 3:30 PM

Can anyone else confirm this:

 

When opening a project in PP .. the Activity Monitor only shows one hyerthread ( out of 24 )  active while the program opens .. and it takes a long time.

 

This is a 12 Core ( 24 hyperthreads ) Mac Pro

 

Does it happen on a 8 Core Mac Pro?

 

Thanks for checking.

    I'm on a 8-core.  When the project is opening, I get one core working at max.  When the media is loading on the timeline, I get all cores working, bouncing around from 50%-100% workload. 

     

    It doesn't take too long to open, but I guess it could depend a lot on the size of the project, amount of media, cache files, etc.

    Opening a project is more disk intensive than anything else, as PP verifies that all files are where it thinks they should be.

    Thanks for the response.

     

    I thought if I paid enough and bought the fastest RAID .. I would get more than 1/2 of 12 cores to load a project.

     

    Any other solutions?

     

    I just upgraded to 10.7.3 and it's still the same.

    Opening files is a pretty serial event and not one that can be easily parallelized without the risk of corrupting things badly.  It's not surprising that only one core gets tapped when doing that.  No amount of expensive/fast RAID is going to make the software use more CPU resources to load a project.  Regardless of the software you're running.

    Thanks Jason .. Unfortunatly your reply makes sense.

     

    A 45 min. SD clip takes me 4 min to load ..

     

    It has several linked compositions and audio tracks.

     

    I guess it is what it is .
