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 default
from the file set when I posted v4.
Stefan, please see cover letter above and let us know if that sounds
acceptable to you.
Yes, the results you posted look fine. Thanks!
Stefan
Thanks for your answer.
Please don't pull this for now, I found issues with patch 3, which I
didn't double check before including it in v4, sorry.
I'll find issue and post a v5.
Regards,
Pierrick
