Tips to Improve Poor Render Performance?
on Sep 13, 2012 at 2:42:14 pm

Hi, I'm in the process of setting up the Adobe After Effects CS6 Render Engine on our render node but it is rendering very slowly.

Here are the specs for the node:

Windows Server 2008 R2 Service Pack 1 - 64Bit operating system
Processor: AMD Opteron Processor 6168 1.90 GHZ (4 Processors)
RAM: (32 GB)

Here are my multiprocessor settings:

Installed RAM: 32.00 GB
Current RAM Usage: 7.06 GB
Allowed RAM Usage: 29.00 GB
Process ID: 6492
Application Name: After Effects
Min Needed Memory: 0.40
Max Usable Memory: 32.00
Max Allowed Memory: 29.00
Current Memory: 0.32
Current Priority: 1 - High

This render node was initially acquired for rendering Cinema 4D files and thus far it has served its purpose by rendering very quickly. We are trying to now utilize AE's render engine on it to speed things up a bit but we are running into issues. We purchased a license of the Adobe Creative Cloud and installed it on the node and ran a test render based on a file that we knew took about an hour to render locally on our workstations but it took 14+ hours to render the final product which is in line with reason. We tested the same file utilizing two more of our machines (not nodes) as a part of the entire render configuration and the render was complete in less than an hour. The crux of our problem seems to be gross under performance on the node but we can't figure out why that is...

We've tried turning multi-processing on and off on the node, we've updated AE to the most recent version, we aren't using any weird 3rd party plugins or anything out of the ordinary. Any ideas?

Watch the Performance tab of the Windows Task Manager or Resource Monitor while rendering to get a sense of how high CPU, memory, disk, and network utilization is. If any one of these is maxed out while the others are under capacity, you have identified the bottleneck.

Another possibility: your server is running Ae CS6 on an unsupported OS. The system requirements call for Windows 7 SP1 (64 bit).
