Subject: [linus:master] [sched/fair] a53ce18cac: hackbench.throughput 47.4%
improvement
Hello,
kernel test robot noticed a 47.4% improvement of hackbench.throughput due to commit:
commit: a53ce18cacb477dd0513c607f187d16f0fa96f71 ("sched/fair: Sanitize vruntime of entity being migrated")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: hackbench
on test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480+ (Sapphire Rapids) with 256G memory
with following parameters:
nr_threads: 100%
iterations: 4
mode: process
ipc: socket
cpufreq_governor: performance
In addition to that, the commit also has performance change on the following tests:
+------------------+------------------------------------------------------------------------------------------------+
| testcase: change | hackbench: hackbench.throughput 8.3% improvement |
| test machine | 104 threads 2 sockets (Skylake) with 192G memory |
| test parameters | cpufreq_governor=performance |
| | ipc=socket |
| | iterations=4 |
| | mode=process |
| | nr_threads=100% |
+------------------+------------------------------------------------------------------------------------------------+
This means that the performance regression reported at the link below
has been resolved:
