Illustrator CS6 - Lagging - extremely slow!!

Hi I have the same problem with Illustrator CS6. Overnight (no changes in the machine i am aware of) copying a set of drawings in an 325k file (just vector not embedded bitmap) to the clipboard takes 3 minutes instead of the usual 5 second, and the machine display a message

Filename @150% (CMYK preview)

or

Filename @150% (RGB preview)

This is win 10, all updated, 32 GB of RAM, reboot did not help, I did optimize window and i tried to cut and paste the artwork in a different file with no success

HELP !!!!!!!!

I had the same issue and realized it occurred after I had set up a keyword command for dictation.

It resulted in an extreme lag, unresponsive commands, and strokes created while hovering with pen or mouse.

I changed those settings in my Mac (by unchecking "enable dictation keyword phrase") and the AI issue was resolved.

After upgraded my PC with better resources there is improvement, now remain to purchase a good graphic card and i think our most big problem is that we use integrated or gaming graphic card instead of the one special made for this type of applications like Nvidia Tesla or Quadro.
Did someone have this types of graphic card to test with AI?

After trying everything on this list, and some disabling of navigator and playing with preferences, NOTHING WORKED...

But i did solve it! but uninstalling and installing previous verion cc 2015   oh well..

Some tips that have helped my lagging Illustrator issue (I previously posted a couple days ago):

- I was using many Adobe PDFs in my Illustrator file, which are much larger in size -- Instead: using JPG, PNG or copy/pasted Vectors are much smaller (I am working on a portfolio which includes mockups and various types of files)

- Saving, Closing and Reopening your Illustrator file seems to 'refresh' it a bit, making it run smoother

Hope this helps!

I believe it has to do with how large the Illustrator file you're working on is, which is affected predominantly by the images you import into it. When I begin a new Ai file, the program works quite seamlessly. When you're working in strictly a vector file, it too runs pretty smoothly. However, when completing bigger projects and importing image files (whether Adobe PDF, JPG, PNG, etc), Illustrator starts to run extremely slow. I am having this problem while working on my portfolio, which includes various file types, including large image files.

I don't have a solution at the moment, but I wonder if there's a way to shrink image file sizes that you import into your Illustrator file? Almost like using a 'zipped' version in your document as you work? If anyone knows if this is possible or has additional help, do tell!

I too find it very nerve wracking to work when EVERY task/move in the program includes a 5-10+ second spinning pinwheel.

Question -- Has anyone actually had these issues while working in a new/small/vector-only file? I haven't. The lag only comes when I'm working on extensive files.

Also, specs:

MacBook Pro w/ Retina (13 inch) - bought NEW Jan 2015

OS X El Capitan - Version 10.11.5

Processor: 2.6 GHz Intel Core i5

Memory: 8GB 1600 MHz DDR3

Startup Disk: Macintosh HD

Graphics: Intel Iris 1536 MB

Hope my input helps anyone pinpoint the problem!

I had the same problem when I moved to a MAC PRO. The AMD cards don't give any GPU help. Turn off hardware acceleration. The good thing is the xeon CPU is fast enough to move reasonably heavy files around.

Several Changes Made The Difference!
Read: Improve Illustrator performance on Windows

The article is thorough and covers EVERYTHING!

1. Changed Virtual memory Settings:
2. Optimized Windows
3. Increased Available memory
4. Hide Layers and remove Thumbnails!
5. Hide Navigator Panel
6. Hide Links Panel ( That really fixed mine )
7. Restart the computer - ID'd excess startup apps - and disabled

Good luck and happy illustrating!

It is shame, that adobe "support" is limited to "make new user account" and "please upgrade to latest version".

In my case Illustrator causes serious performance impact on everything. Every other program gets sluggish. Temporary helped installing older version of product, but after a day or two - problem gets back again. So I've found different solution, which also have it's flaws - installing alternative software Affinity Designer. So far no impact on performance.

I wil try the trick with colour space and printer though...

I think I've found the cause why the system is becoming slow....well, in my setup. I think It's because o the Wacom tablet(intuos pro). When I unplug the tablet I don't have unworkable slowdown. It slows down a bit, but I still can work on a decent speed.
