lkp@...org Subject: [lkp-robot] [mm] 18333aa4c7: vm-scalability.throughput -16.9% regression Greeting, FYI, we noticed a -16.9% regression of vm-scalability.throughput due to commit: commit: 18333aa4c7c9779667b94832669f51e1a0da35bd ("mm: readahead: increase maximum readahead window") https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master in testcase: vm-scalability on test machine: 4 threads Intel(R) Core(TM) i5-2300 CPU @ 2.80GHz with 4G memory with following parameters: runtime: 300s test: lru-file-readtwice cpufreq_governor: performance test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us. test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/ Details are as below: --------------------------------------------------------------------------------------------------> To
