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.

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.

swoga‌  You have a good point about excluding directories. I for example have some wedding photography sets I do not need Lightroom trying to identify every single wedding guest in a group shot, and even if I did want to include the directory and only cared about the wedding party I do not have a way to exclude everyone else. That may help but still doesn't address the core issue.

Still the same problem, It took also 2 days and notice that it miss close to 50% of the faces. I have notice that when I started to check individual picture. Many of the ppl where not even selected even there where a perfect head shot.

Hope in the next release they will fix the speed issue and the quality of the selection.

Another interface bug that I found: when editing the confirmed faces to screen out the ones that are wrong, LR regularly does not register an edit. I.e. I type in a new name for a face and confirm, but the tag does not change. This happens especially when I edit several faces in quick succession. So I have to make the edit, and then watch the interface to confirm that the wrong face really disappears.

Does anyone else see the same thing?

Once you are in "slow mode" you have to wait for every action. Even selecting multiple images with ctrl+click (on win) takes sometimes more than 5 seconds. I speak from the white border that says: "yes, you have selected an image"

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

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.

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.

And ditto here too. Great idea, poor implmentation. In it's current state this feature is totally unusable (other than a handful of small galleries). Trying to work with 1000's or 10's of thousands of images grinds the process to a crawl. Constanst screen reloads, lags, freezes etc. Needs major work. Rather fustrating as it's the main reason I upgraded from LR5 which itself was only purchased a few months back. I'm seriously condsidering a request for refund.

Now I'm experiencing data loss.  The faces I've detected just got kicked out -- like 1,500 of them.

I called Adobe, waited on hold for a while, and some guy picked up, acting like I was bothering him (??).  When I started explaining my problem, he HUNG UP -- !!

This version is junk -- sorry, it is.
