Question

LR CC 7.5 Poor Performance Moving Images

First up: I have performed all of the steps in here (NB: Fresh install of LR CC on machine).
Machine Specs:
AMD TR4 1950x,

32GB Quad Channel RAM,
Intel 600P m.2 x2 RAID 1 as main disk with additional m.2 SSD's acting as caches.
Running Windows 10 Pro v.10.0.17134.

So, the machine is no slouch.

Problem:
Moving photos around on the main disk takes considerably longer time that expected.

Disk monitor shows approximately 2-11MB/s of activity for LR (with no other significant programs running).

Photos have been imported as 12 bit Compressed RAW+JPEGS from a pair of Nikon D500's.

Photos imported with only embedded & sidecar previews. No smart previews are generated.

Lightroom catalog size: 6.36GB

Lightroom catalog images: Approx. 315,000

LR has 30GB set for Cache on separate SSD

What's going on Adobe?

    File -> Optimize catalog dramatically improved move-speed for me. I have a brand new 2TB SSD in an iMac 2012.

    Impressive, I believe this contributed to the improved speed.

    Well, the thing is that I noticed low performance when moving pictures after I started using this new disk. Slower than before, actually. So I optimized the catalog and got an immediate improvement. My old disk was a hybrid, so the new one is not really very much faster. Actually there are other operations that are remarkably slow. One is updating the counts for number of pictures per folder, that seems to be done every time I open the catalog. This is slower than before, and I do not understand why.

    Don't do the move within Lightroom.

    Instead, do the move with your operating system, then reconnect the photos inside of Lightroom to their new location, instructions are here: Adobe Lightroom - Find moved or missing files and folders

      I came to a similar thought that I should just do that.

      It does however mean matching the catalog with the new location of the images once done, which is inconvenient if I am to set and forget aka leave the computer to move images.

      I'm more wondering why there is so much overhead or why there is such poor performance?

        There have been numerous reports of users losing files when moving a large amount (100+) of images from inside LR. See this post for more details: Lightroom: Moving files, resulted in deleting the files | Photoshop Family Customer Community

        The best advice is to not move files once imported into LR and use Picks, Ratings, Labels, Keywords and Collections for "organizing" your images.Here's what I suggest when you do need to move a large number files. Scroll down to reply #13: Re: How do I move my pictures to external hard drive?

        Concerning poor performance is this also happening when importing, editing, or exporting images?

        Just some thoughts outside the box.

        a. Move is a multi function. First copy to the new location on HDD confirm the operation, then remove the files from the original.

        b. When you are moving a large volume of files it requires a lot of HDD space.

        c. Ensure you have lots of free disk space on the HDDs involved at least 25% of the drive capacity.

        d. If you are moving from an internal drive to an external via usb cable the the performance will controlled by the weakest link in the operation, most likely the usb cable.

        I have plenty of free hard drive space (more than 50% free on the main SSDs and around 65% free on the cache SSD's).

        No external copying is taking place - I am simply moving the files into separate folders within the same volume.
