Premier pro is rendering slow on my Z820

Hi Jeff

Can you turn off the GPU (go to software Mercury Engine) and retest?

[Ericbowen]

Yes that means the drive speed is not keeping up with the rest of the system and the CPU’s are waiting on the disk. The lan testing shows the latency of data is lowering the CPU load to the point Hyperthreading stops.

[Jeff Schaap] “This makes me suspect that we are hitting a network bandwidth limitation.”

… or storage?

[Jeff Schaap] “disk I/O topped out”

[Jeff Schaap] “the system can’t get quick enough access to the files…”

Couldn’t agree more. Seems clear to me: move the file to an SSD or other faster storage, retest. Congrats on figuring out the bottleneck.

So I wanted to get back on here and share what we found. When we moved the footage to an internal SSD with a read Speed of 550MB (OCZ VECTOR) the everything started working much faster and preforming as expected. The System chewed thought the DPX files without a problem.

Thanks for your help.
