Photoshop 23.5 extremely slow saving process

hey all,

I might have found a cause and solution for this issue. After updating from Photoshop 2022 to 2023, I also started seeing super slow psd file save time and my file size increased by 4-5 times (I save psd files of images 5000-6000px, 300ppi in 16 bit mode. usually the file size is around ~100 mb, now it is 500-600mb). I also work with CR2 and JPG files.

After doing some tests I realized that for me it was having camera raw 15 that was causing slow saving speed and large psd files. After I downgraded to Camera Raw 14.5, and still using Photoshop 2023, my files size and saving speed went back to the original! And overall the photoshop performance has become much faster.

Can anyone else with this issue confirm that Camera Raw 14.5 solved the issue?

The menu is on the bottom of the document window:

Sorry, but I have no idea where that menu is.  I've checked all available Settings menus and submenus....

Also, to reiterate, the opening file sizes haven't changed, nor has my workflow in PS, so focusing in on file size/types is, I think, misleading to the root cause of the problem.  I've been using CR3 files for several years.  I've been using Photoshop with these files for several years.  I've used PS on a MBPro and while the processing time for various functions, such as "Actions" were getting very slow over time, that had to do with the computer itself being a 2016 model, more limited RAM, VRAM, and PS requiring more and more horsepower.  But SAVING time was never an issue.  

Now, with a sooped up MacStudio with all the latest bells, whistles and RAMs, the "Actions" functions perform very quickly.  But the SAVING functions are slower than ever on PS!  And I also point out these are files with relatively few layers or clipping masks- like 2 or 3.  And I'm also hitting limits on file size now!  You can't go much more than 3 or 4 layers and you can't save it as a PS file!  How is that "professional" software?  Ad agencies and creative studios don't just just 2 or 3 layers for their work....

Again, all this points to PS File Saving structure: speed and bloat.

What does Photoshop report for Document Sizes and Document Dimensions?

I'm having the same trouble. PS2023 is noticeably slower saving!   It isn't related to the files I'm saving. (That would imply I save the same files all the time...) It is related to a PS 2023 issue.  The files I'm opening are either CR2, CR3 or JPG, (nothing exotic)  and once opened through CameraRAW, it's all the same when you "SAVE AS PSD."   It takes 40 (seconds minimum) or more to save in PSD format a simple color file with even just 1 or 2 clipping masks!  This has been doing this since the 2023 updates.  

Incidentally, I am using a brand new Mac Studio with the super-duper Ultra Chip with 128GB RAM and 48cores VRAM with M1 Chipset, sidewinder missles, headsup displays and look-down radar... in short, this, according to Tim Cook, is the fastest, most powerful computer on the market today, designed for power users working with graphics and video....  So, I think I can safely eliminate all consideration of any possible issues related to "my computer isn't up to date" or "my computer does not have enough RAM" or does not have enough of anything...

And the slowness is irrelevant to whether the "Use Graphics Processor" is turned on or off. Same sloooooooow response in saving time.

I originally got the MacStudio because my 2016 MacBook was getting slower and slower with each new update of PS... "Action" scripts were taking so long I could almost go get a cup of tea while I waited.  But "Saving a file" didn't seem to be a particular issue, just part of the overall slowness of the aging chip set.

Now, however, it is apparent.  Other kinds of files for other programs (e.g., MS office, iMovie) are noticeably faster.  Also, importantly, for this discussion, PS "Actions" scripts are must faster in execution than with the MB Pro. But, the "SAVING A FILE" is  MUCH SLOWER. Excrutiatingly slow.

So, in conclusion, the previous gentleman (Mr. Kubicki) has a Windows machine and complains of file saving slowness with PS 2023.  I have a super-duper hepped up MacStudio and file saving is really slow, practically the same as the MB Pro, yet "Actions" scripts are much faster.  So I think we can conclude that the culprit is the "SAVE" function on PS 2023...

One final note on "Saving" issues... working with the same kinds of files generated by the same camera, I am now often hitting 2GB file size limits on saving, with the saving process terminated, and PS suggesting I save in another file format!  This didn't happen before either.  

Something is amiss with the "Save" funtion in PS 2023...

Can you share the file you're having trouble with? Post a URL to the file using CC files or dropbox, or something similar to share the file.

it looks like the artboards are the cause (there are 22 in the document). The problem disappears when I hide them. Turning on or off Generating Image Assets has no effect on saving speed.
