What should I write in macOS catalina (bigSure) when starting QEMU to speed up the system in virtual machines?

Question

QEMU

I start like this:

qemu-system-x86_64 \
  -m 8000 \
  -vga virtio \
  -display default,show-cursor=on \
  -usb \
  -device usb-tablet \
  -drive file=/Users/zaza/win10.img \
  -accel hvf \
  -cpu host

win10 what slows down the star (((window for three minutes opens
the same Windows on the praralis flies (but the parales does not suit for many reasons)
