[mm/lru] 0d6b06c622: fio.write_iops -12.3% regression
by kernel test robot
Greeting,
FYI, we noticed a -12.3% regression of fio.write_iops due to commit:
commit: 0d6b06c6225334459e562738d3bcaac71343c9d0 ("mm/lru: replace pgdat lru_lock with lruvec lock")
https://github.com/alexshi/linux.git lruv19.2
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
runtime: 200s
nr_task: 50%
time_based: tb
rw: randrw
bs: 4k
ioengine: mmap
test_size: 200G
cpufreq_governor: performance
ucode: 0x5002f01
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.

[core/entry] 36ad6f6f66: unixbench.score 9.0% improvement
by kernel test robot
Greeting,
FYI, we noticed a 9.0% improvement of unixbench.score due to commit:
commit: 36ad6f6f66ea701911375051f156ab62d649f879 ("[PATCH] core/entry: Report syscall correctly for trace and audit")
url: https://github.com/0day-ci/linux/commits/Kees-Cook/core-entry-Report-sysc...
base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git e8878ab825450c9ac07a0fc22e1f66fdb62b4f72
in testcase: unixbench
on test machine: 96 threads Intel(R) Xeon(R) CPU @ 2.30GHz with 128G memory
with following parameters:
runtime: 300s
nr_task: 1
test: syscall
cpufreq_governor: performance
ucode: 0x4002f01
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
Details are as below:
