Comparing the performance of Fedora 23, Fedora 23 with Qubes kernel, Docker container based on fedora:23 image and an arbitrary Fedora 23 TemplateVM based AppVM (Xen domain) inside the Qubes OS R3.1. A Fedora 23 TemplateVM is the standard AppVM in Qubes OS R3.1, therefore the performance inside an AppVM based on this template usually represents the performance of an arbitrary application running under the Qubes OS R3.1. The Docker version used was 1.11.1 and the Fedora spin used was Workstation x86_64. The version of PTS used for tests was Phoronix Test Suite v6.4.0m2 (Hasvik).
