Adobe Illustrator and Photoshop are painfully slow, more so than any other design editors I've used in the past. Can Adobe do more to optimize their software experience? I'm not even doing anything complicated, yet things slow down considerably on my relatively new machine. I've had slowdowns on all the machines I've owned, some more than others. I had the same problem on my iMac, Surface Pro 6 and now Razer Blade 15. Adobe XD and Adobe Fresco are the only applications that seem well optimized, and the rest are fairly slow in comparison.

The Community forums are user forums, so you're mostly reaching volunteers like me and other users. If you'd like the Illustrator team to see your suggestion, try posting to the Illustrator Uservoice page. That's where they look for bug reports and feature requests.
