To late to build packages in arm64/aarch64 on qemu

Hi, all

I'm tring to build packages in arm64/aarch64 on
qemu-system-aarch64. But it's too late in comparision to
amd64 on bhyve. For example, `make package-recursive' of
devel/binutils on qemu takes 67 times of bhyve [1]. I found
that it's difference caused from disk geometry factors such
as stripesize, cylinders according to firmware and heads
according to firmware [2]. 

I also try to test in qcow2 format with cache-size 4 GB, but
nothing progress:

root@vm:/vm/test # qemu-system-aarch64 -machine virt -cpu cortex-a57 -smp 4 -m 8G,maxmem=8G -name test -blockdev driver=file,node-name=hd0,filename=FreeBSD-13.0-CURRENT-arm64-aarch64.qcow2 -blockdev driver=qcow2,node-name=hda,file=hd0,overlap-check=none,cache-size=4294967296 -device virtio-blk-device,drive=hda -nographic -monitor telnet::5045,server,nowait,nodelay -serial telnet::5044,server,nowait,nodelay -bios QEMU_EFI.fd

root@vm:~ # telnet localhost 5044
