Subject: [mm] 2d146aa3aa: vm-scalability.throughput -36.4% regression
Greeting,
FYI, we noticed a -36.4% regression of vm-scalability.throughput due to commit:
commit: 2d146aa3aa842d7f5065802556b4f9a2c6e8ef12 ("mm: memcontrol: switch to rstat")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: vm-scalability
on test machine: 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
runtime: 300s
size: 1T
test: lru-shm
cpufreq_governor: performance
ucode: 0x5003006
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
In addition to that, the commit also has significant impact on the following tests:
+------------------+-------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.null.ops_per_sec -45.9% regression |
| test machine | 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory |
| test parameters | class=device |
| | cpufreq_governor=performance |
| | disk=1HDD |
| | nr_threads=100% |
| | testtime=60s |
| | ucode=0x5003006 |
