Importing in LIghtroom is  Painfully slow in Classic.  After I upgraded to Classic I am seeing importing going from 2-3 minutes to 10-20 minutes.

Sometimes it takes 5 minutes for anything to start importing. 

This is now not a professional option with this decrease in importing speed.

This has been a problem for several month and Adobe hasn't come up with a fix yet?  They develop the problem, aren't they smart enough to fix their own mistake?  This is BS.  I've been waiting over an hour to unplug my iPhone so I can continue with my daily activities, but I've now got to wait on LR to finish it's imports.  Never had this problem before recent update.  Thanks a lot Adobe!

Steve, i totally agree with you. After 6 months there should be a fix available for this issue... The performance issues in LR are just annoying...

Hi,
is there any update with this issue. I've got the same problem now. To import 700 images takes hours with 100% CPU usage when they come from SD card. Copying with the OS is done in minutes,

This reply was created from a merged topic originally titled Lightroom import very slow.

The most recent version of Lightroom imports photos really slowly. It's taken me over 30 minutes to import 110 photos. In previous versions an entire 32GB card would take around 10 minutes. Please fix this!

Adobe software is usually excellent, but I need it to function normaly so I can work on schedule.

Iain, according to John Ellis, a Lightroom Champion—and therefore an unimpeachable source of knowledge—, no one is seeing this problem.  You and I are one...no, two in a million.  We should be buying Lotto tickets together.  LOL

This reply was created from a merged topic originally titled Lightroom Classic import from a card - just so slow.

Since the latest update, when I import from my SD card, nothing happens for ages. Then suddenly I see that Lightroom has imported 1 image, when in fact 20 are already on the hard drive. I have checked my PC and Lightroom has maxed out with all the memory on my PC at 98%

I finally broke away from Lightroom and jumped the boat to Capture One 11 Pro. Yes, I'm an Adobe Cloud subscriber but Adobe doesn't care and I don't want to fight it anymore. I'd rather put money down on something else, that just works and won't give me the same problems I've had over so many years without any address.

And with that, I can finally "Unfollow" this thread and never be bothered by the ever lasting issue that doesn't get resolved for years ... cya!

Importing is slow for me as well. Some stats, if that helps:

9/17: 103 photos, from SD card - 16:32 (copy and import - 8:14)
9/21: 67 photos, from SD card - 11:38 (copy and import - 4:42)
10/13: 129 photos, from SD card - 26:20 (copy and import - 12:27)
10/19: 287 photos, from SD card - 48:25 (copy and import - 29:13)
10/25: 210 photos, from SD card - 40:49 (copy and import - 28:00)

I'm usually current with updates, so the dates reflect pre- and post-version 8.

What OS are you using? Did you upgrade OS between 9/21 and 10/13?

Currently, Windows 10, Version 1083 (OS Biuld 17134.345).

I'm not sure if the version changed since 9/21, but I do try to keep my OS updated, so it's probably whatever was current for MS at the time. (But Windows 10 regardless)

Ok. That question was more of a Mac user question.  My normal first port of call since there are not widespread reports of import slowness with 8.0 on Windows is to test the integrity of your install.  Sometimes the state of your machine at install/update time is a little wonky and a clean reinstall will shake out those issues. 

Close Lightroom
Restart the computer
Use the Adobe Creative Cloud App to uninstall Lightroom Classic CC
Restart the computer
Install Lightroom Classic CC via the Creative Cloud App without launching any other programs.
Restart the computer
Launch Lightroom
Wait 5 minutes

I uninstalled and reinstalled (keeping preferences) Lr from the CC app. Import time is the same - 277 photos, from SD card - 57:00 (copy and import - 36:00)

Ok. Now that the reinstall is complete - let's reset your preferences:

A Preference File will survive a Lightroom uninstall/reinstall.

Reset Procedure:

1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom. 
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.

Does the import performance improve after resetting the preferences?

OK, I reset preferences, but I don't think it really improved things.

60 photos from SD card - 14:24 (copy and import - 8:55)

BTW, I should mention that this is a "Copy as DNG" import (which has been the case all along - I just want to be clear).  I wouldn't think that should be the issue here, as way back when there was a time when the "Copy as DNG" was much faster. IOW, I've always imported as DNGs, and at some point it got much, much slower.

So are the two times listed for Copy as DNG, and then Copy (no dng)?

Sorry, I should have been more clear.

I've always been importing as DNG. The total time it takes to complete all activity involved in importing is the bigger number. In my latest import, that would be 14:24.
The "copy and import" refers to the first thing that Lr tells me it's doing - "copy and import" is displayed over a progress bar. That action lasts as long as what is in the parentheses. In my latest import, that would be 8:55. When that action completes, Lr tells me that it's "performing 2 actions" with 2 progress bars below. That action lasts as long as total time less the time in the parentheses. In my latest import, that would be 5:29 (14:24 minus 8:55).

Ok. I am trying to duplicate. I shot 62 raw files with a Canon 5D Mark II and set them to import (Copy as DNG) on a Win 10 (1803) Dell Laptop (modest spec 8GB ram, i5-6300, 250 GB disk with 137GB free) - Lexar USB 3 card reader in Lightroom 8.0:

Elapsed time to import and convert to DNG: 2 Minutes 12.95 seconds to import completion dialog.  1.33 GB of data after import/convert. 

I think we need to look at your drive configuration next. I am running about 7x your speed on a modest machine. Give me a run-down of your drives, where Lightroom is stored, where the catalog is stored and where the images are stored and I will see if I can spot anything there.

I'm on a SurfacePro 2017 (i5-7300, 8GB RAM) with a 256GB SSD (23 GB free) (Toshiba THNSN0256GTYA). Everything is local - Lr and Lr catalog (v. 8.0). Images come from an SD card (Sony 32GB SDHC U1) through a USB adapter (Rocketek Surface Ext.).

I'm happy to go down this path of checking my hardware, but this problem actually started happening on my HP laptop (Pavilion dv7), which I don't have access to right now. Lr and Lr were both local there as well, and the SD card was read from the built-in card reader. But, however you want to proceed is good with me.

I am concerned about the amount of free space you have. In general, Windows devices need to have 20% of the drive free to give maximum efficiency.  Can you temporarily offload some items to create 50 GB of free space and see what happens to your import performance?

I freed up 62GB of space and then imported 102 photos. 18:07 was the total import time.

Before disk space free up: 14.4 seconds/image
After disk space free up: 10.6 seconds/image

Well, that's an improvement but it is still slower than the 2.1 seconds per image I am seeing on Windows. Just for another data point, I ran the same 62 image import on a MBP with better specs and I cam in a 1 Minute 33 seconds or 1.5 seconds per image. 

Based upon that, I guess I curious how a non-Lightroom data transfer goes. If you take those 102 photos and use Windows Explorer to copy them to a folder on your Desktop - what is the elapsed time for the data transfer?

I copied 196 photos to my HDD from the SD card, and that took 5:31. And then I imported them into Lr from the HDD. Results: 17:40 (copy and import - 7:11 [from HDD])

Raw OS copy speed:

Duplicating your test, the same 62 images on a direct disk file copy on my Windows laptop take 40 seconds or .65 images/second. 

Compared with your test of 1.68 images/second 

Your file transfer rate is less than half of mine with Lightroom excluded from the equation.

Interesting.

Doing some math - and I hope this is right:

Import from the HDD into Lr (so excluding SD-HDD transfer): 5.0 sec/image
Importing from the SD card into Lr: 11.0 sec/image
Your import time:  2.1 sec/image

So, to sum up: Freeing up hard drive space decreased import time a little. Importing from the HDD decreased import time by over half. Your import time is less by half again.

SD Card transfer appears to be a bottleneck. This is a built in card reader. Do you have access to  an external reader?

The card reader I'm using is an external reader. The Surface Pro 2017 doesn't have an SD reader.

While the SD reader may be slowing things down, I'm not sure it's the main problem. Your import from SD card is twice as fast as my import from HDD. Do you know what your import time is from the HDD?

At this point we may be looking at simple hardware speed differences.

Happy Thanksgiving!

I find it hard to believe that this is a hardware issue.  We have similarly spec'd setups* - i5, 8GB RAM, Win 10 1083. In fact, my i5-7300U processor is faster than your i5-6300 processor. (I don't know what your HDD is, but mine is an SSD.) When we exclude reading from SD card, your import time is more than four times faster than mine - 5.4 sec/image vs. 1.2 sec/image. 

 I'll grant that there are a couple of things on my end that can improve performance (free HDD space, faster SD card/card reader), but even taking those into account, your import speed is multiples of mine. Given that our machines are just about identical in hardware specs, I don't see where there's room for improvement that would give me a 4x speed boost.

 *That is, of course, if the time you mentioned on 11/19 (1.2 sec/image) was on the Dell and not the MBP
