by kernel test robot

Greeting, FYI, we noticed a 376.0% improvement of aim7.jobs-per-min due to commit: commit: 079f9927c7bfa026d963db1455197159ebe5b534 ("ext4: gracefully handle ext4_break_layouts() failure during truncate") https://git.kernel.org/cgit/linux/kernel/git/tytso/ext4.git dev in testcase: aim7 on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory with following parameters: disk: 1BRD_48G fs: ext4 test: creat-clo load: 1000 cpufreq_governor: performance test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system. test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/ Details are as below:

[mm/page_alloc.c] 60f9751638: will-it-scale.per_process_ops 9.1% improvement

by kernel test robot

Greeting, FYI, we noticed a 9.1% improvement of will-it-scale.per_process_ops due to commit: commit: 60f97516388a0fc63bcaf31a1cb81d22d4b765b4 ("mm/page_alloc.c: Set ppc->high fraction default to 512") https://git.kernel.org/cgit/linux/kernel/git/saeed/linux.git net-next-mlx4 in testcase: will-it-scale on test machine: 192 threads Skylake-SP with 256G memory with following parameters: nr_task: 100% mode: process test: page_fault2 cpufreq_governor: performance test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two. test-url: https://github.com/antonblanchard/will-it-scale In addition to that, the commit also has significant impact on the following tests: +------------------+-----------------------------------------------------------------------+ | testcase: change | aim7: aim7.jobs-per-min 9.8% improvement |

[btrfs] 302167c50b: fio.write_bw_MBps -12.4% regression

by kernel test robot

Greeting, FYI, we noticed a -12.4% regression of fio.write_bw_MBps due to commit: commit: 302167c50b32e7fccc98994a91d40ddbbab04e52 ("btrfs: don't end the transaction for delayed refs in throttle")
