I am a 20+ year Apple user, new to Linux and trying to make a slow transition away from macOS to Linux.
At the moment I am dual booting my machine with macOS 11.1 and Manjaro 20.2.
I am already getting about 60% of my work done in Linux and so far I am very happy about that.

Something I noticed is that my u-he plugins perform worse on Linux compared with how they perform on macOS.
My system:
* Intel Xeon W-3235 12-Core CPU @ 3.30GHz
* 48GB 2666MHz
* 2TB SSD
* AMD Radeon Pro 580X
* RME Fireface UFX in CC Mode
** ALSA (jack2 is installed, but not configured)
* Manjaro GNOME 20.2
* 5.9.1-1-rt19-MANJARO kernel
* Bitwig Studio 3.3.1
** 1024 samples block size @ 44100 Hz
** Plug-in Hosting Mode: Individually
** Prefer VST 3 over VST 2: enabled
** Prefer 64 bit over 32 bit: enabled
* u-he plugins revision 10721
** multi-core setting enabled where possible
Test scenario:
I made two test projects (one with only Bitwig devices and one with only u-he devices) and ran them with the exact same settings in macOS and Manjaro. While the Bitwig only test project performed more or less identical on both operating systems, the u-he only project performed much worse on Linux.
The u-he project consists of 20 tracks with Satin, Presswerk, ACE, Bazille, Hive, Repro 5 and a return with Twangstrom and ColourCopy. On macOS there is about 50% CPU headroom left. On Linux I can only playback about 5 tracks before the DSP Performance Graph starts to touch the roof and to create crackles.
Do other users have comparable results to mine? Of course, it would be great if I can achieve comparable performance to macOS on Linux.
Here's a couple of screenshots I made:

Many thanks for your help and the exchange in advance!
