Lightroom 6 / CC2015 - Facial Recognition Terribly Slow, not using all of CPU or GPU, still keeps going when paused.

This is actually a couple of issue but wondering if others are experiencing it and worked through it.

I am using a Dual Xeon CPU 3.2 ghz Mac Pro, Catalog on SSD, Images files on Mirrored Pair, Dedicated GPU (max I can install in my version of Mac Pro) and hardware acceleration enabled in Lightroom.

I watched the Lightroom 6 Facial Recognition tutorial which leaves out a lot of the bulk editing and says basically let it loose on your whole catalog.. NOT recommended.

I started out with a couple small portrait galleries that identified a couple hundred total people to seed facial recognition so it didn't suggest everyone is the first person I confirmed (which it will do otherwise). I have also optimized my catalog multiple times.

I have encountered the following serious performance issues and bugs with Facial Recognition.:

  • Lightroom Facial Recognition goes to a ridiculous crawl after about 2000 images to be confirmed. (i.e. 2000-2300 in a couple hours, 800-1200 in the next 12 hours)
  • Lightroom becomes largely unresponsive after having a fair number of images to be confirmed, even after pausing Address and Facial Recognition. So even selecting 4 rows of images can take 5 minutes with several long pauses.
  • Once I select and click confirm it takes up to 2 minutes to update the "to be confirmed" list again.
  • When I click on an individual at the top of the page, pause facial recognition and address lookup it still continues to "Look for similar faces" [BUG!!!!!!!!] even though all I want to do is just confirm some individuals more quickly in bulk with the images already identified.. not continue to look for more as a work around for the painfully slow responsiveness of the module.

The odd part is that with all of the performance issues Lightroom will not use more than 20-30% of my two Xeon CPUs, barely touches my GPU (<10% CPU, 30% memory), my and no more than 35% of my memory. Computer Temps are also barely above startup temperatures and 15-25 degrees cooler than when I run other applications which will consume my entire CPU and memory if I let it. I have explored Lightroom's settings but seen nothing further I can configure to speed it all up.  I have also attempted the operation on images on the SSD, my drobo (known to be slow), an independent fast disk I have, and a pair of raided disks and have the same issues.

I will also note that all of my other applications seem to continue to operate just fine.. the slowness seems to be contained to the Lightroom application itself.

    I am reviewing 220K photos -- it's extremely painful.  So painful that my wife doesn't want me on the computer any more, since all I'm trying to do (for hours) is combat the swelling tide of thousands of photos.

    And you name it -- tires, sand, grass -- it tries to name it -- not to mention pets!

    I'm surprised at how poor it is in differentiating different people, tires, pets, etc. -- many of them it says are all the same person / pet -- ??

    And the speed is unbelievably slow.

    This is almost so painful I wish I'd never started it -- sad.

      I have about the same number of photos (~225k) and I am just letting it do a set of directories at a time now. The batch of 40000 pre-sorted, pre-keyworded (as I had everyone's name already in a keyword which it does not use) photos took from Friday evening till Monday morning for it just to go through. I decided until it has recognized all of the faces at this point I am not going to doing any more confirming, tagging, etc. Facial Recognition at this point is far from becoming part of my work flow if it is going to be this slow.

        Same here, insanely slow to do anything.

        Just trying to rename one face takes a good 45 seconds or more before the UI updates with the name change.

          Same thing on Win7 with i7-4770K 3,5 GHz, 16GB Ram and GeForce GTX 970.

          Slow, slower, slowest and no System load while tagging faces

            Similar issues here. When showing a few hundert unnamed people, the interactive face tagging is so slow that it is almost unusable. Usually several seconds waiting time between clicks, frequent "beach balls", and also a bug where I can not select some of the faces when using Conmmand-click.

            The whole purpose of this feature is to speed up a time consuming and tedious process. An unresponsive interface does not help in any way. I hope an update will fix this.

            I am running an 2011 iMac 27 inch with HDD (no SSD), 12 GB RAM.

              Since writing the original post I can too confirm I am experiencing the "can't control-select/command-select" some images but can select others as well. I have had it happen when I have no images selected and just wanting to do one image or when I have dozens of other images selected.

              I will also clarify the 2000-2300 images reference above, that is actually "unnamed people".. I haven't been watching the number of indexed images as closely since it doesn't display. 

              But do know again last night it 12 hours I set it upon 15000 images (raw image count, not unnamed people) which almost all people had a fair profile already established this morning it still has 5000 to go.

                Same issue. I have 62500 pictures in my catalog and it took about 2 days to analyze. Tagging people is painfully slow. I now have tagged about 2500 faces and 77000 are unnamed. Many of them will stay unnamed but LR does not have an ignore face feature like Picasa.
