This small patch series makes it easy to spot big performance regressions, so that they can later be investigated. For example: $ ./aggregate.perl --sort-by=regression --subsection "without libpcre" v2.14.3 v2.15.1 v2.16.2 p4220-log-grep-engines.sh +5.0% p4220-log-grep-engines.2 0.60(0.58+0.02) 0.63(0.59+0.04) v2.14.3 v2.15.1 +4.5% p4220-log-grep-engines.10 0.67(0.64+0.03) 0.70(0.67+0.02) v2.14.3 v2.15.1 +1.7% p4220-log-grep-engines.5 0.58(0.57+0.01) 0.59(0.59+0.00) v2.14.3 v2.15.1 +1.7% p4220-log-grep-engines.6 0.58(0.58+0.00) 0.59(0.56+0.02) v2.14.3 v2.15.1 +1.7% p4220-log-grep-engines.17 0.58(0.57+0.01) 0.59(0.56+0.02) v2.14.3 v2.15.1 +1.7% p4220-log-grep-engines.1 0.60(0.58+0.01) 0.61(0.60+0.01) v2.14.3 v2.15.1 +1.6% p4220-log-grep-engines.13 0.64(0.63+0.02) 0.65(0.63+0.01) v2.14.3 v2.15.1 +1.5% p4220-log-grep-engines.9 0.67(0.66+0.01) 0.68(0.67+0.01) v2.14.3 v2.15.1 +0.0% p4220-log-grep-engines.14 0.65(0.62+0.02) 0.65(0.63+0.02) v2.14.3 v2.15.1 +0.0% p4220-log-grep-engines.18 0.58(0.57+0.00) 0.58(0.56+0.02) v2.14.3 v2.15.1 -1.5% p4220-log-grep-engines.13 0.65(0.63+0.01) 0.64(0.62+0.01) v2.15.1 v2.16.2 -1.5% p4220-log-grep-engines.14 0.65(0.63+0.02) 0.64(0.60+0.03) v2.15.1 v2.16.2 -1.6% p4220-log-grep-engines.1 0.61(0.60+0.01) 0.60(0.58+0.02) v2.15.1 v2.16.2 -1.7% p4220-log-grep-engines.5 0.59(0.59+0.00) 0.58(0.55+0.02) v2.15.1 v2.16.2 -1.7% p4220-log-grep-engines.6 0.59(0.56+0.02) 0.58(0.55+0.02) v2.15.1 v2.16.2 -1.7% p4220-log-grep-engines.18 0.58(0.56+0.02) 0.57(0.55+0.02) v2.15.1 v2.16.2 -2.9% p4220-log-grep-engines.9 0.68(0.67+0.01) 0.66(0.64+0.02) v2.15.1 v2.16.2 -3.4% p4220-log-grep-engines.17 0.59(0.56+0.02) 0.57(0.55+0.01) v2.15.1 v2.16.2 -4.3% p4220-log-grep-engines.10 0.70(0.67+0.02) 0.67(0.66+0.01) v2.15.1 v2.16.2 -4.8% p4220-log-grep-engines.2 0.63(0.59+0.04) 0.60(0.57+0.03) v2.15.1 v2.16.2 Since V1, the indent issues have been fixed and the name of the option has been changed to --sort-by=regression (from --sortbyregression) as suggested by Junio.
