Subject: [bristot:dl_server_v6_try9] [sched/rt] 3d2f07d039:
unixbench.throughput -5.0% regression
Hello,
kernel test robot noticed a -5.0% regression of unixbench.throughput on:
commit: 3d2f07d039b863082bbc4c9c541ea2b8fa9a5b1a ("sched/rt: Remove default bandwidth control")
git://git.kernel.org/cgit/linux/kernel/git/bristot/linux dl_server_v6_try9
testcase: unixbench
test machine: 36 threads 1 sockets Intel(R) Core(TM) i9-10980XE CPU @ 3.00GHz (Cascade Lake) with 128G memory
parameters:
runtime: 300s
nr_task: 1
test: context1
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+-------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.mutex.ops_per_sec 142.6% improvement |
| test machine | 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory |
| test parameters | cpufreq_governor=performance |
| | nr_threads=100% |
| | test=mutex |
| | testtime=60s |
+------------------+-------------------------------------------------------------------------------------------+
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@...el.com>
