High CPU and disk usage when I use the Tor Browser

Hello, when I start Tor Browser and browse websites I notice a high CPU and disk usage on my host system (win 10, virtualbox 6.1.30). I don’t have this issue when I open images or files with tor browser though. It also doesn’t seem to be an issue with security settings of the tor browser (safest or plain).

Tor Browser Consumes 100% CPU after Clock Sync or Suspend/Resume?

Otherwise: Tor Browser Reliability Recommendations
