From my personal experience, Windows 11 Is more responsive and faster than Windows 10, shutdown and boot times Included.

What about ram & cpu usage ?

With typical programs open (browser/etc.), I idle at less than 10% usage. If you're on a budget or pre-built machine, it might be worth waiting until there's provable metrics. But personally, I have not noticed a negative impact.

It is possible virtualization-based security is the culprit, but I've heard a variety of things:

Far from being as accurate as a benchmark, seeing Windows 11 requirements gives me a good hint it won't be lighter than Windows 10 (at least on the ram) :
- Windows 10

• RAM: 1 gigabyte (GB) for 32-bit or 2 GB for 64-bit
  
• Processor: 1 gigahertz (GHz) or faster processor or SoC 
  

- Windows 11

• RAM: 4 gigabytes (GB) or greater.
  
• Processor: 1 gigahertz (GHz) or faster with two or more cores on a compatible 64-bit processor or system on a chip (SoC)
  

And I feel like there won't be any need to migrate for few years still, but we'll see!
