Greeting,
FYI, we noticed a 1.2% improvement of pigz.throughput due to commit:
commit: ca7277e7aea43bbfb96a378bac115f6d51c4e1a0 ("mm: do not add anon pages to
LRU")
git://bee.sh.intel.com/git/aaron/linux.git zone_range_lock
in testcase: reaim
on test machine: 256 threads Phi with 96G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: aim9
cpufreq_governor: performance
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
Details are as below:
