Hi Skylar,

Thanks for you answer, very useful but I have got a silly question:

Using the proxy relationship do we know if TSM is going to spread the work 
accross all the nodes of the cluster of just only above the nodes that have 
enable the scheduler ¿?

Thanks for your help,

Regards,

I've found that setting RESOURCEUTILIZATION as high as practical helps a
lot, especially if you have lots of files.

You can also break up the work across however many nodes that you have
by using proxy node relationships:
