There is a thread with attempt to collect CO export benchmark statistics on different machines
So everyone could use this information to build/buy a good computer for CO workflow.
I suggest to improve this bench with fixed set of RAW files, so the collected bench data would be more accurate: it will depend mostly on computer specification (CPU and GPU first), but not on RAW files type (Canon, Nikon, Sony and all other RAW types affect export speed).
So here is the benchmark algorithm:
Download the following zip with RAW files and unpack them to some folder
50 photos made with Canon 5D mk3, size about 1.3GB. Theese photos were made by myself so no property rights are violated 😊
Start CO and ensure that GPU acceleration is enabled: menu Edit - Preferences - General tab - Hardware acceleration - Processing set to Auto (if it was set to "Never" before, you need to restart CO so changes are applied)
- Open RAW files that were downloaded on step 1 and wait until they are fully imported (previews are built by CO).
Set up the following export parameters:
ICC Profile: sRGB IEC61966-2.1
Resolution: 300 px/in
Scale: Fixed 100%
Open with: None
❗️ It is very important to set up export with theese parameters! Otherwise the bench results won't be reliable!
Make the first export (GPU accelerated) noting the duration of this process.
At least one export process is needed. However it would be great if you'll be able to make it 2 or 3 times, because results may vary depending on HDD caching, computer background processes and others. Take the shortest time duration - it is the first bench result.
Disable GPU acceleration: menu Edit - Preferences - General tab - Hardware acceleration - Processing set to Never. Restart the CO.
Make the second export (no GPU acceleration) in a similar way as in step 5.
That will be the second bench result.
Make a post at this thread with the following format:
- Computer type (PC/Mac) and model (if any) and OS version
- CPU+GPU - benchmark time 1
- CPU only - benchmark time 2
- CPU model
- GPU model
- CO version
You can also make the second benchmark for TIFF export format - it would be good addition to previous JPEG benchmark. Current version of CO (11.0) is limited in perfomance when exporting to JPEG format due to internal algorithms. So TIFF export would show better results in some circumstances, consuming more hardware power. Theese TIFF export parameters are needed to be set up:

Here is a myself-written Windows utility that will help to easily calculate benchmark results: it analyzes all files in selected folder and automatically calculates time span between opening of first file for writing and last file modifying.

Suggestions for benchmark improvements are very welcomed!
Hope my post doesn't look to rigorous 😊
The only goal of this thread is to help each other with selecting hardware components for best CO workflow experience.
