Hello,
kernel test robot noticed a 13.0% improvement of hackbench.throughput on:
commit: c8d312e039030edab25836a326bcaeb2a3d4db14 ("slub: Delay freezing of partial slabs")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: hackbench
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory
parameters:
nr_threads: 50%
iterations: 4
