Whonix is slow.

I’m running whonix in kvm. It gets very slow or freezes. Is there a solution?

You need to specify more what are the errors, or make a quick video so we can see what is your problem.

Is it getting slow when you have a lot of tabs or applications running?

Maybe try increasing the RAM on the workstation, you can also reduce the RAM on the gateway to 256 and it will run in cli mode
