Hi all, we have compared scheduler performance for kernel-4.6.0-0.rc5.git0.1.wastedcores against kernel-4.6.0-0.rc5.git0.1.el7. *Summary: *against all expectations* kernel-4.6.0-0.rc5.git0.1.wastedcores performs on average 20% WORSE than the regular kernel. * Results for different servers: SPECjbb2005: - karkulka-02.lab.eng.brq.redhat.com-htON <http://perf-desktop.brq.redhat.com/SPECjbb/.vs./karkulka-02.lab.eng.brq.redhat.com-htON/4.6.0-0.rc5.git0.1.el7.x86_64-throughput-performancevs4.6.0-0.rc5.git0.1.wastedcores.el7.x86_64-throughput-performance/Result-2016-Apr-26_03h05m44sResult-2016-Apr-29_22h17m07s/specjbb2005.html> - kiff-01.cluster-qe.lab.eng.brq.redhat.com-htON <http://perf-desktop.brq.redhat.com/SPECjbb/.vs./kiff-01.cluster-qe.lab.eng.brq.redhat.com-htON/4.6.0-0.rc5.git0.1.el7.x86_64-throughput-performancevs4.6.0-0.rc5.git0.1.wastedcores.el7.x86_64-throughput-performance/Result-2016-Apr-26_01h47m36sResult-2016-Apr-30_02h21m38s/specjbb2005.html> SPECjvm2008: - karkulka-02.lab.eng.brq.redhat.com-htON <http://perf-desktop.brq.redhat.com/SPECjvm/.vs./karkulka-02.lab.eng.brq.redhat.com-htON/4.6.0-0.rc5.git0.1.el7.x86_64-throughput-performancevs4.6.0-0.rc5.git0.1.wastedcores.el7.x86_64-throughput-performance/Result-2016-Apr-26_07h58m09sResult-2016-Apr-30_03h09m23s/SPECjvm2008.html> - kiff-01.cluster-qe.lab.eng.brq.redhat.com-htON <http://perf-desktop.brq.redhat.com/SPECjvm/.vs./kiff-01.cluster-qe.lab.eng.brq.redhat.com-htON/4.6.0-0.rc5.git0.1.el7.x86_64-throughput-performancevs4.6.0-0.rc5.git0.1.wastedcores.el7.x86_64-throughput-performance/Result-2016-Apr-26_05h06m46sResult-2016-Apr-30_05h40m50s/SPECjvm2008.html> Linpack and Stream: - karkulka-02.lab.eng.brq.redhat.com-htON <http://perf-desktop.brq.redhat.com/LinpackAndStream/.vs./karkulka-02.lab.eng.brq.redhat.com-htON/4.6.0-0.rc5.git0.1.el7.x86_64-throughput-performancevs4.6.0-0.rc5.git0.1.wastedcores.el7.x86_64-throughput-performance/Results-2016-Apr-25_21h38m02sResults-2016-Apr-29_16h22m44s/linpackAndStreamResults.html> - kiff-01.cluster-qe.lab.eng.brq.redhat.com-htON <http://perf-desktop.brq.redhat.com/LinpackAndStream/.vs./kiff-01.cluster-qe.lab.eng.brq.redhat.com-htON/4.6.0-0.rc5.git0.1.el7.x86_64-throughput-performancevs4.6.0-0.rc5.git0.1.wastedcores.el7.x86_64-throughput-performance/Results-2016-Apr-25_21h36m46sResults-2016-Apr-29_21h37m03s/linpackAndStreamResults.html> Any comments, questions, suggestions?
