1. Re: Saving and Opening to my Samsung EVO 960 1TB (Nvme SSD) is very slow
Trevor.Dennis Jan 15, 2017 1:42 PM (in response to bildform.)What are your Scratch space settings? If that is using a different, slower, drive then that might be what is going on, but a minute still sounds way too long. Something is definitely not right IMO.
What operating system are you using? If Windows 10, open up Resource Monitor and see if you can see where the bottleneck is.

2. Re: Saving and Opening to my Samsung EVO 960 1TB (Nvme SSD) is very slow
bildform. Jan 16, 2017 3:08 AM (in response to Trevor.Dennis)I am using Windows 10 and all drivers are up to date.
The task manager shows writing speeds of around 0 to 10 mb/s. If just I copy 5 1Gb files it is done in a few seconds... why cannot photoshop do that?
I did some testing. I turned on "disable compression of psd and psb files" >>> So now I have a 11 GB file that saved in 10 seconds :-)
At least the speed is how it is supposed to be. But 11 GB is just to big.
When compression is working/on I would expect the cpu to start doing some work but it is not. So I guess Photoshop is writing as fast as it can compress the psd file, which is not much because the cpu is not being utilized correctly.

Trevor.Dennis Jan 16, 2017 3:22 AM (in response to bildform.)I'm off to my bed, so can you have a look at these threads while waiting for someone else to join the thread. This would have been a perfect question Chris Cox, but alas, he no longer works for Adobe.
I forgot the link :-(

We know that issue is not with your M.2 drive, but rather with PSD compression being slow, so I am going to change your subject line. Shout if you'd rather it said something else, and one of the other mods will fix it for you.
Incidentally, you have mentioned PSD files, but I assume you are actually talking about PSB files? AFAIK it is completely automatic and I don't think you even get the option to use PSD over 4Gb. I am not about to test it though
Good luck.

4. Re: Compressing Large PSD File When Saving Very Slow
bildform. Jan 24, 2017 9:57 AM (in response to Trevor.Dennis)Ok, I read some threads and di a few tests. So I guess, the problem is that Photoshop only uses one core when compressing the psd file. No wonder it is slow in writing the file (I have i7-6800k)
Is there a way for Photoshop to use more than one core when compressing? I mean, winrar can do it...

6. Re: Compressing Large PSD File When Saving Very Slow
Trevor.Dennis Jan 28, 2017 12:32 PM (in response to bildform.)This time last year, we might of got a heads up on your question from Photoshop Development Team member Chris Cox, who used to post in this forum, but alas, Chris is no longer with Adobe. Your best chance of an informed opinion would to ask the same question on the Feedback site, where Jeff Tranberry hangs out.
I just had a look and found this discussion over there.
Photoshop CC 2017: Very slow to open even small PSD files | Photoshop Family Customer Community
Do you absolutely need to have PSD/PSB compression turned on?
What are your space limitations?
How many drives do you have?
I don't have uber fast M.2 drives on my five year old system, but with 15 drives, I have a pair of Samsung 256Gb Pro, and a Samsung 1Tb EVO. I planed to use the 1Tb SSD as a Projects drive, and bump older files to archive on the mechanical HDDs, but it has turned out that I still have space on that 1Tb SSD four years later. I just checked and it only has 200Gb free.
The point I am making again here, is do you really need to use compression with your PSD files when they have such a negative affect on overall performance?
