Subject: [kbuild] 6a3193cdd5: netperf.Throughput_tps -11.9% regression
Greeting,
FYI, we noticed a -11.9% regression of netperf.Throughput_tps due to commit:
commit: 6a3193cdd5e5b96ac65f04ee42555c216da332af ("kbuild: lto: Merge module sections if and only if CONFIG_LTO_CLANG is enabled")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: netperf
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
ip: ipv4
runtime: 300s
nr_threads: 200%
cluster: cs-localhost
test: SCTP_RR
cpufreq_governor: performance
ucode: 0x5003006
test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/
If you fix the issue, kindly add following tag
