Parallel creation of previews in Lightroom with active Hyperthreading on an SixCore Intel Xeon E5 1650 v3, Lr 8.3.1

[ChristopherK.]

Greetings from Germany,

I'm using a HP Workstation Z440 with a SixCore Intel Xeon E5 1650 v3, with 32 GB of ECC RAM and a nVidia Quadro K4200 graphics card as well as the latest updates.

If I turn off hyperthreading in the BIOS and have not set the hook for parallel creation of previews in Lightroom, then, as it should be, first the images are copied and then the previews are created.

But if I turn hyperthreading on, the hook does not stay set, nevertheless a parallel preparation of the previews takes place.

Can someone explain why that is? The support had no answer.

Thanks in advance!

Hi ChristopherK,

I'd recommend that you post this query on our Lightroom community as well: Lightroom Classic | Photoshop Family Customer Community

Our Engineering team do monitor this space and look for major feature requests/feedback from our valuable users like you to shape the product further.

Thanks,

Akash

For my own benefit in this forum can you illustrate the outcomes of "turn off hyperthreading in the BIOS and have not set the hook for parallel creation of previews in Lightroom" for editors?

Fascinating . . .

The link above does not work.  Can you tell me where this topic can be found now?  I'd like more information on lightroom > preferences > performance > "generate previews in parallel".

Thank you.

That link points to the old feedback forum. Last year Adobe migrated some of the content in that old forum to this forum, but unfortunately, much of it was discarded.

I suggest you start a new thread and provide more detail about what you're interested in understanding.
