Performance has been measured with this automated fio benchmark, with
original instructions from Stefan [1].
$ git clone https://github.com/pbo-linaro/qemu-linux-stack -b
x86_64_io_benchmark
$ cd qemu-linux-stack
$ ./build.sh
$ ./run.sh /path/to/qemu-system-x86_64
[1] https://lore.kernel.org/qemu-devel/20260202185233.GC405548@fedora/
Results are on 20 runs and expressed in kIOPS:
reference: mean=239.2 std_dev=3.48
with_series: mean=238.5 std_dev=3.46
Performance is on par, and within standard deviation.
Does it look better to you Michael?

better for sure. is there a reason you dropped stefanha
from CC? he suggested these tests...
I didn't to that intentionally, it seems like he was not added by

Stefan, please see cover letter above and let us know if that sounds
acceptable to you.
Regards,
Pierrick
