[linux-next:master] [drivers/char/mem] 1b057bd800: stress-ng.splice.ops_per_sec -99.8% regression
From: kernel test robot
Date: Tue Oct 17 2023 - 11:08:16 EST
Hello,
kernel test robot noticed a -99.8% regression of stress-ng.splice.ops_per_sec on:
commit: 1b057bd800c3ea0c926191d7950cd2365eddc9bb ("drivers/char/mem: implement splice() for /dev/zero, /dev/full")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
class: pipe
test: splice
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+-------------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.splice.ops_per_sec 38.9% improvement |
| test machine | 36 threads 1 sockets Intel(R) Core(TM) i9-10980XE CPU @ 3.00GHz (Cascade Lake) with 128G memory |
| test parameters | class=os |
| | cpufreq_governor=performance |
| | disk=1HDD |
| | fs=ext4 |
| | nr_threads=1 |
| | test=splice |
| | testtime=60s |
