Why is Photoshop 25.3.1 so slow?

[2Charlie]

Has anyone notice how slow the release 25.3.1 is or is it just me? Here's what I have.

1. 4.42GB .psb file size
2.  Saving to SanDisk 2TB Extreme Portable SSD
3. Blackmagic Design disk speed test showed 802.6MB/s write and 725.1MB/s read on a 5GB file
4.  MacBook Pro M1 Max with 64GB RAM running Ventura 13.5.2 (22G91)
5. Memory Usage: Let Photoshop use 43415MB (70%)
6. Graphics Processor Settings: Use Graphics Processor is checked
7. Scratch Disk: SanDisk 2TB Extreme Portable SSD drive is checked

I zoomed to 100% and apply a Remove tool tone one spot. It took about 13.41 seconds to complete. And then I tried to save the two layers file. The bottom layer is the actual image and the second layer is a blank layer I'm using to apply the remove tool on just one spot. It took 1 minutes 59 seconds just to save this file to my SanDisk 2TB Extreme Portable SSD. It took 17.78 seconds to simply open the file.

So, is this normal or is it something wrong with this specific release?

@2Charlie are you certain the file is a psd or a psb format? Files that large usually are converted to psb.

How fast was it saving to your local HD?

[2Charlie]

Sorry, my mistake...it's PSB file format.

Go to Preferences - File Handling. Disable compression for psd and psb files. The resulting files will be larger on disk but will save and open much faster as there is no need to compress and uncompress.

With this option turned off, applying the remove tool still take as long or two seconds longer but saving has gone down to 14.48 seconds.

By the way, saving to the internal disk of the MBP, takes much less...around 7 seconds. However, using the remove tool is still very slow.

@2Charlie what is your Photoshop settings/Image Processing Remove Tool set to?

[2Charlie]

It is set at "Faster".

@2Charlie have you tried changing the tool option to not process after each brush stroke?
