Since my Christmas-gift arrived in time (even before), I’ve now installed PL8 (Elite) on the MacMini M4 Pro (64GB / 14CPU/20GPU / 1TB). Pics will be stored on external Samsung 990 Pro 4 TB SSDs.
Can you pls share your experience with the settings which work best for M4 Pro?
Of the settings you show, the top slider makes a noticeable difference…but only for file export. My 8/8/16 M1 MacBook Air from 2020 is best set to about 4 parallel exports. Your 14/20/64 M4 Mini might be best at different settings.
I recommend that you export a set of images (a mix of small and large files from different camera bodies in order to get some variation) with different slider settings and note the overall export times. Often, the very first export is a tad slower which means that you should run that measurement twice.
Einstellungsdateien & Korrekturprotokoll are fairly personal preferences, I uncheck the automatic I/E and set the protocol to 500.
DeepPRIME Beschleunigung can be left at automatic. It’s relevant for the Deep* denoising methods and for export only.
I did a few tests on my M3 Pro MacBook Pro shortly after I got it and also set 7 parallel exports. I recently reduced it to 4 again, which is what I had on my M1 MacBook Pro (essentially the same hardware @platypus has). Why did I reduce it? Because, in practice, I found it was taking a long time to export any individual files so, perceptually at least, having many running at once did not seem to be a huge gain. I should probably test again and learn not to stare at the screen while exporting.
In the end, testing is the only way to tune that number meaningfully. Note that the number of CPU and GPU cores has much less bearing on results if you’re using any of the DeepPRIME noise reductions regularly. In this case, the 16 Neural Engine cores are doing the heavy lifting.
I usually keep exports at 2 threads, as I prefer to retain full control of my computer to continue to edit or to work in PhotoMechanic. At 4 threads+, one more or less should wait for the export to finish. Two threads mean both images process at full speed.
Oh, yes, there is no do-it all-setting, Yours suits your needs and that is what you want.
I usually batch export at the end of a session, when I’m away from the computer.
Balancing export speed vs. usability during export is something that @blumax should do, based on his own needs, images and hardware. Only then can @blumax get a setting to be happy with.
