Photoshop 21.2: TIFF coming from LR Classic are incredibly slow to save

How to replicate:
  1. Import a raw image in LR classic
  2. Set LR classic "export to photoshop" parameters to TIFF srgb 8bpc compression ZIP
  3. Export the image to PS June 2020 update.
  4. Edit the image in PS and save it.
Saving process is INCREDIBLY SLOW. It takes 30-60 seconds to save an image that before June 2020 update took 3-4 seconds. 

Configuration:
Windows 10 up to date.
i7, SSD, LR classic up to date, PS June 2020, nvidia geforce 980

Can you replicate / fix this problem?

Thanks

While not a solution to your problem, if you're exporting a TIFF you're losing image quality by saving it as a compressed TIFF, and going through 2 unnecessary steps (compression and decompression). You also don't specify how much memory you have on your machine.

Tiff zip compression doesn’t affect image quality at all. Also, before a june 2020 I had no problems. I have 64 GB or rams at 3000MHz

There was a bug fixed recently where Tiff Compression - though enabled - was not happening. I suspect you were used to the speed of the uncompressed Tiff thinking it was a compressed file.

If I create a new image in PS, add some colors/gradients and save it as tiff 8bpc srgb zip compressed it’s really fast. Even if I edit it again and save again.

So the problem is only from tiff coming from LR Classic.

Was the fix you are talking about regarding PS or Lr-PS integration?

Maybe fixing it programmers did something wrong. You should investigate and try to replicate.

I ran a test.

Two raw files
1 Sent to PS at Tiff 16 Bit No Compression
1 Sent to PS at Tiff 8 Bit Zip Compression
To each file I duplicated the layer and set the blend mode to Screen
Closed each file forcing a save
First file took 3 seconds to return to Lightroom
Second took 4 seconds to return to Lightroom

So, I cannot replicate your time differential.

Could I record a screen capture of the problem? What additional info should I provide?

Also: did you run the test on windows 10 up to date?

Try turning off ZIP compression. If you've already saved files with Zip compression, do a Save As to make sure the settings aren't still set to ZIP.

Thanks! I ran some additional tests. Here the situation:

  • tiff 8 bit - compression: LZW ---> FAST
  • tiff 16 bit - compression: ZIP ---> FAST
  • tiff 8 bit - compression: ZIP ---> REALLY SLOW
I'm talking about single flat layer (so no layer compression)

The problem is visible both coming from LR and native PS images (contrary to what I said before)

I'm sure that 8 bit ZIP compression wasn't so slow before 21.2 update. Maybe before 21.2 update the compression was broken? Or maybe you introduced a bug with the last update.

I just tested 8 bit and 16 bit images with Image ZIP, Layer ZIP, and with both set to ZIP. The PS 20.0.6 and PS 21.2.0 save times are identical.
  • tiff 16 bit - compression: ZIP ---> FAST
  • tiff 8 bit - compression: ZIP ---> REALLY SLOW
On my Windows 10 system the 8 bit ZIP save time is faster than 16 bit as expected. Clearly there's something wrong with your system. You can try a Preferences reset. Scroll down to 'Reset Photoshop Preferences' at the below link:
