Subject: [tip:timers/core] [timers] 7ee9887703: netperf.Throughput_Mbps
-1.2% regression
Hello,
kernel test robot noticed a -1.2% regression of netperf.Throughput_Mbps on:
commit: 7ee988770326fca440472200c3eb58935fe712f6 ("timers: Implement the hierarchical pull model")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git timers/core
testcase: netperf
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
parameters:
ip: ipv4
runtime: 300s
nr_threads: 200%
cluster: cs-localhost
test: SCTP_STREAM
cpufreq_governor: performance
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
