Subject: [linus:master] [x86] 47ee3f1dd9:
phoronix-test-suite.ior.2MB.DefaultTestDirectory.mb_s -21.7% regression
hi, Linus,
we reported "[linus:master] [x86] adfcf4231b: blogbench.read_score -10.9% regression"
on
https://lore.kernel.org/lkml/202305041446.71d46724-yujie.liu@intel.com/
however, as you pointed out, the blogbench is a "*horrifically* bad benchmark
for this case", Feng Tang also made a debug patch to confirm this.
now we noticed 47ee3f1dd9 is fix patch for adfcf4231b, just as we found for
adfcf4231b, this commit could also cause performance regression or improvement
for different cases. actually only this case is a regression, all others are
improvement (we normally pick regression as title to report).
below are detail data. hope they could be for your information about the
possible performance impact of this change.
Hello,
kernel test robot noticed a -21.7% regression of phoronix-test-suite.ior.2MB.DefaultTestDirectory.mb_s on:
