I did try with the file on a ramdisk $ sudo mount -o size=3G -t tmpfs none /ramdisk$ /usr/local/bin/qemu-system-x86_64 -name Windows10 -S -machine pc-i440fx-2.4,accel=kvm,usb=off [...] -mem-prealloc -mem-path /ramdisk
with that, the speed of the VM is acceptable. It will not take your breath away, but it is reasonable.
