What at first appeared was a snapping issue, which sent me down a road of exploring and turning off all snap and dynamic guide options, turns out to be some kind of performance issue. Illustrator lags (jerks) when moving objects including anchor points. I have not been successful finding anything on the forum that seems to address my exact issue.
Latest updates have been installed.
iMac (Retina 5K, 27-inch, Late 2015)
4 GHz Intel Core i7
32 GB 1867 MHz DDR3
AMD Radeon R9 M395X 4096 MB
Thanks in advance for any help

Wow, nothing?

When nobody has had this issue and/or nobody can reproduce it (because of lack of this specific hardware) then it might actually happen that you get no answer. Should not, but does happen. 90% of people here are not Adobe employees. On top of that: holiday season.

Same issues here - also 5K iMac (1 month old), with 64Gb ram. Anything more than a simple document results in the spinning beach ball or dreadful lag. Interestingly, my 5 year old MacBook (1st generation retina, 8Gb Ram), copes with the most complex documents without much issue. Photoshop etc all runs fine and as expected on the iMac - definitely an Illustrator issue, and judging from the various threads I've read, seems specific to the 5K iMac.

Lee78UK, thank you so much for your reply.
With all of the Illustrator users out there I thought for sure I was not the only one having issues.
Photoshop and Illustrator is getting so slow at startup too.
Ah well...what can ya do?

I am also in a 5k iMac and Illustrator is stupid slow. Seems to mostly be if there are placed graphics—jpeg, psd, png. It's painful to work in. I'm considering going back to 2015—for other apps as well, it seems 2017 has been really buggy with little enhancement.

I have also the same issue with exact same hardware and cannot believe that a machine that costs so much money is not capable of working smoothly with graphic apps. Absolutely annoying!

I have a 5K i7 iMac at work, and Adobe apps run fine. But I bought a 5K i5 iMac for home, and Photoshop runs terribly on it. I haven't noticed any issues with Illustrator, though. I think the 5K i5 iMac is like the iPad 3: woefully underpowered for the number of pixels it needs to push.

Has anything fixed these slow issues? I just started using a 5K 27" late 2015 iMac and all of the Creative Suite applications run much slower than my 2012 MacBook Pro.

To CTC-NH. Creative Suite? as in CS6 or older, or do you mean some generation of Creative Cloud? 2018 releases seem problematic for some, as are 2017 for these folks, so they went back to the 2015.3.1 Illustrator and Photoshop 2015.5.1 (AKA version 17.0.1) I'm sure it's dependent on what operating system they are running on and the 5K iMac from 2015 needs at least Yosemite, which is the same as the minimum requirement for Adobe Creative Cloud apps.

Latest 2018 version of the Suite and latest Apple OS. I posted the comment three months ago and it's not changed a bit.

Have you tried changing your display to a non-HighDPI mode, which is 2560 x 1440 for your 27" iMac. That should give your iMac greater speed by not having to deal with 4 times as much screen to refresh.

I have the same problem, Im using Illustrator 2019 on a brand new 5k iMac Retina and ilustrator is running REALLY slow.
How do I change the display mode to an non HD?

Yes, its disabled. But what does that have to do with Illustrator?

It interferes with Illustrator in some sort.
Sorry, but that's about all that we know on the forums.

It looks like you have a real powerhouse computer there, however I'm seeing a lot of these posts (look how we have 20 people just here, marking the same issue). It seems that although that card is fully supported on a Windows machine, (see Adobe Illustrator system requirements) it seems that on the Mac, they don't list video cards as specifically. I HIGHLY recommend Monika Gause suggestion to use the Bug/Feature request page. If enough people here submit the same issue, they're more likely to attend to it.
In the meantime, have you tried using the GPU performance button or preferences to see if that resolves the issue for the time-being?
