Subject: [linus:master] [sched/fair] 155213a2ae: unixbench.throughput 23.2%
regression
Hello,
we reported a "22.9% regression of unixbench.throughput" for this patch in
https://lore.kernel.org/all/202507150846.538fc133-lkp@intel.com/
where there are some discussions.
later we also reported
"[tip:sched/core] [sched/fair] 155213a2ae: unixbench.throughput 20.2% regression"
in
https://lore.kernel.org/all/202507281046.e71b853a-lkp@intel.com/
since now the commit is in mainline, we rebuild the kernel and rerun the tests,
still observed similar regression. below full report is just FYI.
kernel test robot noticed a 23.2% regression of unixbench.throughput on:
commit: 155213a2aed42c85361bf4f5c817f5cb68951c3b ("sched/fair: Bump sd->max_newidle_lb_cost when newidle balance fails")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master 91325f31afc1026de28665cf1a7b6e157fa4d39d]
[still regression on linux-next/master 43c3c17f0c805882d1b48818b1085747a68c80ec]
testcase: unixbench
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
runtime: 300s
