P: CS6 Slow compared to CS5.1 with large files

good point ray! i would like to hear an explanation too?

and chris, also i checked the event scripts. it is turned off.

I have the latest version as well (not counting the small processor speed update that has been made last month) and have issues too.

BTW, the latest version comes with either a Radeon 5770 or 5870. If the 5870 would mean an end to my issues I will be buying it without blinking or thinking.

There is no MacPro with 16cores. The highest performance model currently available is the 3.06Ghz 12core (I have the 2.93Ghz 12core).

Maybe you are thinking of 8 cores with 16 threads?

What PC has a regular desktop mainboard (no server board) that hosts 2 processors?

Here is a copy of the file. It doesn't matter which group you move, they all cause a significant slowdown. You might want to turn off layer 1 first (the canvas background rendering) or it is even much worse.

If others feel like it, download it as well and check it too.

the latest generation is the one i didn't tested.
that means that CS6 is only compatible with the latest generation mac pro??
i can imagine that, it's a way to support apple. not to mention that they didn't updated the PROs for decades.

would it be possible for you to test the file on some older mac pro??

Last generation MacPro for me (8/16 core, radeon 4870), and a similarly configured PC (8/16 core, off brand with mixed parts, Radeon 6870).

Me making a movie doesn't make much sense -- it looks the same in CS6 (with thumbnails turned off) as it does in CS5. You see something different from the majority of users, you have the mystery behavior that the rest of us are not seeing and nobody at Adobe can reproduce.

So there is something about your office systems that causes slowdowns and shows progress bars when none should appear.
Did you check the event scripts?

please everyone else on this topic, can you download and make some tests with the test file. is there someone with maxed out last generation mac pro?

ok, i just can't believe this. i tested the file on 3 different macs today at work. they are all different generations and all running 10.6.8 and 10.7.
and all of them are showing exactly the same slow behavior.

what system is the one you have tested?

it is maybe too much to ask, but could you make a movie of the test and share it?

i don't have any third party plug ins as you can see from my sys log. no browsers or anything running at the same time.

The file size doesn't mean much - the document size (pixel count) and compression settings would tell us a lot more. Also, some documents can contain a lot of metadata that adds to the document saving time.
Without seeing the file to figure out why it might take a while to save - we have no way to know whether that time is normal or not.

(repeated since it went into the wrong thread the first time)

I just tried that document on MacOS 10.6.8 and Win7 Photoshop CS6 release -- moving the white dots group is identical in performance to Photoshop 12.0.4, and I never get a progress bar.

I tried with and without the app frame, with and without tabs, with and without all palettes (hiding palettes speeds it up in both versions).

With layer thumbnails on in CS6 I get about 6 FPS updates, without layer thumbnails I get about 35 FPS (12.5% zoom).

So, we need to figure out why you get a progress bar. My guess would be a third party plugin, or an event script (like the ones a certain prepress product installs without your knowledge). Try disabling all third party plugins, and check File -> Scripts -> Scripts Event Manager (it should all be off and empty).
