Photoshop 22.3.2 inexplicably large file sizes, painfully slow saving, Win 10

PS has been running (surprisingly) well for a while, but over the last few days saving a .psd or .tiff has become a nightmare.
For example - file I'm working on at the moment has 4 layers of full pixel coverage with masking and about a dozen adjustment layers. File size is 2.6gb and saving it takes about 5-10 minutes.
A very similar file from a few weeks ago, 1.2gb and saving (whilst originally working on it) was almost instant.

Just opened that earlier one back up replaced one adjustment layer with a slightly different one, save took forever, now it's a huge file. Tried the script for the metadata issue, no change. Any ideas?

Is Photoshop > Preferences > File Handling > Disable Compression of PSD and PSB Files checked?

It is indeed. I tried both ways just to see if it helped speed up saving but it made no difference to save time (though I must admit I forgot to check file size for notable changes!

A 2.6 GB file is pretty big, and will take quite some time to save. There's no way that can be "instant" as you describe it, so those files can't possibly be comparable.

Also, the difference in save times between PSD compression on or off is pretty dramatic. It's on the order of three minutes vs. 15 seconds. So again, you can't be comparing similar files here.

Long save times are mostly CPU encoding, not actually writing to disk. You can check this for yourself in the Task Manager while saving a big file - you'll see the CPU peaking for most of the time, followed by a very brief spike of disk activity. Files with lots of adjustment layers tend to take a long time, they are apparently more math-intensive in the encoding stage.

Hi Davince,

where are you trying to save your files (cloud, computers, external storages)?

Direct to an SSD within the PC that's dedicated to working PS files only.
