Subject: [x86] 97e8f0134a: fio.write_iops 8.6% improvement
Greeting,
FYI, we noticed a 8.6% improvement of fio.write_iops due to commit:
commit: 97e8f0134a2bb794e4885f642724a50979b84f89 ("x86: rework arch_local_irq_restore() to not use popf")
url: https://github.com/0day-ci/linux/commits/Juergen-Gross/x86-major-paravirt-cleanup/20201120-194934
in testcase: fio-basic
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 256G memory
with following parameters:
disk: 2pmem
fs: xfs
mount_option: dax
runtime: 200s
nr_task: 50%
time_based: tb
rw: randwrite
bs: 4k
ioengine: sync
test_size: 200G
cpufreq_governor: performance
ucode: 0x5003003
test-description: Fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user.
