Subject: [linus:master] [slab] ec66e0d599: stress-ng.mmapfiles.ops_per_sec
51.6% regression
Hello,
kernel test robot noticed a 51.6% regression of stress-ng.mmapfiles.ops_per_sec on:
commit: ec66e0d599520ab414db745544e25d80d0ac5054 ("slab: add sheaf support for batching kfree_rcu() operations")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master 23cb64fb76257309e396ea4cec8396d4a1dbae68]
[still regression on linux-next/master fe4d0dea039f2befb93f27569593ec209843b0f5]
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: mmapfiles
cpufreq_governor: performance
