High cpu on host manjaro when i use virtualbox

i have some problems with the usage of virtualbox on manjaro host

i noticed the high cpu when i running vms ( windows and linux like debian os )

i saw more of 100% of cpu usage when i’m running the vms

the version of vbox that i’m using is the 6.1 , it has the guest additions installed by AUR packages
