Subject: [kkdwivedi:arena/tmp-slab-nofix] [bpf,slab] 8e98bca9b3: hackbench.throughput 95.0% regression
Date: Tue, 2 Jun 2026 14:41:09 +0800 [thread overview]
Message-ID: <202606021456.26349ab2-lkp@intel.com> (raw)
Hello,
kernel test robot noticed a 95.0% regression of hackbench.throughput on:
commit: 8e98bca9b3d9cd5861cf495a9f7c85256fbeed4c ("bpf,slab: Add slub-backed allocator for bpf_arena")
https://github.com/kkdwivedi/linux arena/tmp-slab-nofix
testcase: hackbench
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory
parameters:
nr_threads: 1600%
iterations: 4
mode: threads
ipc: socket
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
