From 9d1914d34cebe111a23ab1670633900fd770cec3 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 26 May 2020 15:30:09 -0700 Subject: [PATCH] refperf: Output per-experiment data points Currently, it is necessary to manually edit the console output to see anything more than statistics, and sometimes the statistics can indicate outliers that need more investigation. This commit therefore dumps out the per-experiment measurements, sorted in ascending order, just before dumping out the statistics. Cc: Joel Fernandes (Google) Signed-off-by: Paul E.
