Description of problem:
Virtiofs performance in windows guest have 1/3 compared with RHEL guest

Version-Release number of selected component (if applicable):
virtiofsd-1.5.0-1.el9.x86_64
kernel-5.14.0-284.2.1.el9_2.x86_64
qemu-kvm-7.2.0-11.el9_2.x86_64

Steps to Reproduce:
1.start virtiofsd on host
/usr/libexec/virtiofsd --socket-path=/var/tmp/avocado_poxmt7pc/avocado-vt-vm1-viofs-virtiofsd.sock -o source=/root/avocado/data/avocado-vt/virtio_fs_test/ -o cache=auto
2.boot up win2022/RHEL9.2 guest with virtiofs device.
3.start the virtiofs service  and get the shared disk
4. do fio test on the shared disk.
Ws2022:
"C:\Program Files (x86)\fio\fio\fio.exe" --name=stress --filename=Z:/test_file --ioengine=windowsaio --rw=write/read --direct=1 --bs=4K --size=1G --iodepth=256 --numjobs=128 --runtime=1800 --thread

RHEL9:
/usr/bin/fio --name=stress --filename=/mnt/myfs/test_file --ioengine=libaio --rw=write/read --direct=1 --bs=4K --size=1G --iodepth=256 --numjobs=128 --runtime=1800

Actual results:
It indeed has a performance decreation compared with linux guest, it's about 1/3 compared with RHEL9.2 guest.

Expected results:
Basically there is no big degration compared
