Subject: [vbabka:b4/sheaves-for-all-rebased] [slab] aa8fdb9e25: will-it-scale.per_process_ops 46.5% regression
Date: Tue, 13 Jan 2026 21:57:47 +0800 [thread overview]
Message-ID: <202601132136.77efd6d7-lkp@intel.com> (raw)
Hello,
kernel test robot noticed a 46.5% regression of will-it-scale.per_process_ops on:
commit: aa8fdb9e2516055552de11cabaacde4d77ad7d72 ("slab: refill sheaves from all nodes")
https://git.kernel.org/cgit/linux/kernel/git/vbabka/linux.git b4/sheaves-for-all-rebased
testcase: will-it-scale
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 192 threads 2 sockets Intel(R) Xeon(R) 6740E CPU @ 2.4GHz (Sierra Forest) with 256G memory
parameters:
nr_task: 100%
mode: process
test: mmap2
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
