(CS5) AE Render Performance VERY POOR
on May 19, 2010 at 10:05:53 pm

Hello everyone. I'm going to make this as short and sweet as I can. Thanks in advance for any help.

- System: Mac Pro 8-core Nehalem (2.66GHz), Snow Leopard 10.6.3, ATI Radeon HD 4870

- RAM: 16GB

- Hard Drives: 3TB SATA RAID Internal (caches stored here), 16TB Fiber Channel SAN (render output here)

- AE Settings: Disk Cache Enabled (~10GB on internal RAID); 13GB RAM allocated to AE, 3GB to other apps; Render Multiple Frames Simultaneously enabled, no CPU’s reserved for other applications.

- Project: 720x486 comp, standard DV settings, 14 seconds total; but ONLY first 4 seconds has animation, the rest is still frame. There are only text and particle layers, not even a background.

- Behavior: After setting up the project and clicking “Render”, the render will get through the first 11 frames, then STOP. It holds there for about a minute, and then renders the last of the frames VERY SLOWLY. It finally completed the render after 6 minutes, 23 seconds.

This SAME file rendered in CS4 on a lesser horsepower machine in 30 seconds. I'm stumped.

That is a huge red flag.

Thank you for the tip!

However, after trying 8, 6, 4, 2 processors and then even shutting off multiprocessing, I still get the same result.

Maybe it's a comp issue? I'll see if I have enough time to rebuild this whole thing in CS5-AE, unless you have another suggestion?

Really appreciate your time!
