You could post a link to a raw file from the sample galleries of dpreview.com or any other source that permits downloads - check copyright notices. We could use such a file as reference for simple benchmark measurements. If DxO provided sample files, that would be perfect.

Procedure (must be followed for reproducible measurements)
- Process both images to DNG
- Parallel processing set to 3
- Provided presets or settings, no sliders moved
First column: iMac 27in, 2019, 3.6 GHz 8core i9, 40GB, Radeon Pro 580X 8GB and DPL4 on Mojave.
Second column: M1 MacBook Air, 8+8core, 16GB and DPL4 on Big Sur
- 13 / 14 s @ No Correction
- 33 / 81 s @ NoCorrection plus DeepPrime
- 17 / 21 s @ DxO Standard
- 35 / 81 s @ DxO Standard set to DeepPrime
— / 84 s with parallel processing set to 2
— / 90 s with parallel processing set to 1
Settings play an important role in how much time is used to process the images. Increasing the value for parallel processing does not boost performance that much. I find the sweet spot to be somewhere around 3. Going beyond 3 does not do much good on my systems and batch size.
If we want to play that game seriously, we’d need to define how to set DPL first and also how to run the tests. I’d propose to create a separate thread - including a table hosted in the internet, so that results can be compared more easily. The table should also contain columns for tech specs.
@CaptainPO, if DxO should be interested in such user system benchmarks, could DxO then provide a few resources like test images, the table mentioned above and some brain power on how to set up systems and procedures for comparability?
