Thanks, Oliver,
that´s exactly what I read in the web. But Adobe likes to call itself industry standard. With FCPX and others being so much faster on Mac, I wonder why they don´t put more efforts into this.
Sometimes even After Effects performs better than Premiere Pro.
Rendering is actually pretty OK (it doesn´t even slow down rendering when I work in other programs like photoshop, etc. – I couldn´t do that on my “old” iMac) – what´s most painful though is editing. Sometimes I press the play button and have to wait 2 seconds before it starts playing – same when I stop – it´s really laggy. I have to close the program and reopen it. Then it works a while, but it constantly gets slower and laggier. The situation gets worse the more clips I import into the project. Unfortunately editing is the most important for me – I could render at night when I´m not sitting on the machine, but I need it to work well during the edit process.

Hi Greg, thanks for your reply.
I use the 8-core 3.2GHz Version with 32GB Memory and Radeon Pro Vega 56 8176MB.
I work with SSDs only – internal and external via thunderbolt (2). Occasionally I do a quick edit from a USB3.0 cheap external archive hard drive. The speed isn´t much slower from there.

I edit with ProRes files and h264 (mostly sony a7sII rII and III + Atomos Shogun), there is no real difference with the issue whether I use prores or h264.
The machine is lighting fast for everything else but Premiere Pro.

But as I said, I don´t seem to be the only one with this issue, it´s pretty common from what I read in the last few months. Most people (even long-time Mac users) recommend windows PCs for Premiere Pro because of that. I just talked to a guy who said his MacBook Pro was faster than the iMacPro.

Here is just one of the many threads discussing this issue: https://forums.adobe.com/thread/2456635

Thanks Oliver. That´s interesting. Many, many people in the web seem to have that problem. Quite a few have returned their iMac Pros due to that. From what I understand, that is correct for all Mac(Pro)s, because of their multi-core architecture.

Thanks a lot for your help, Dave and have a nice weekend!
