After a missed installation of Big Sur I recovered the system via time machine. However everything is really slow - opening of Apps, Boot procedure etc.. I reinstalled Big Sur again - but still system ist still not in performance *** it was before the update. Any help from the community what to do?
You can save you and us a lot of time and effort if you do the following:

You need to verify that your Fusion Drive has not become unfused. Please call AppleCare and they will help you sort this out. Your EtreCheck report also indicates SSD too slow - SSD is showing poor performance which means your computer may have a hardware issue.
That was the problem! Thanx a lot for supporting!
I don't really know but it think it's a bug?
I don't know, I'd leave it a bit as big sur was just released and there may be an update to fix your problem later
The system will seem slow for a day or so while new databases are being written. This is normal behavior.
Your welcome.
