VirtualBox Is Still Running Slower Than QEMU-KVM

Recently I ran some benchmarks looking at the performance of the Ubuntu 14.04 LTS development code and from there I tested the bare metal system, the same system with a Linux KVM instance of Ubuntu 14.04 itself, and then afterwards another VM with the same settings and software but using Oracle VM VirtualBox. Here are those early Ubuntu 14.04 Linux virtualization benchmarks.

Ubuntu 13.10 vs. Fedora 20 Benchmarks

To complement the many Ubuntu 13.10 Linux benchmarks I have published on Phoronix since the "Saucy Salamander" premiere in October, I've started several Fedora 20 benchmarks since December. So far I've shared Fedora 19 vs. Fedora 20 benchmarks and Wayland OpenGL benchmarks, besides using Fedora 20 as the base platform for unrelated tests, while today are some Ubuntu 13.10 vs. Fedora 20 performance benchmarks.

Ubuntu 14.04 LTS vs. Red Hat Enterprise Linux 7 Benchmarks

Last week when Red Hat Enterprise Linux 7 Beta 1 was released I was already running RHEL7 benchmarks looking at the performance of Red Hat Enterprise Linux 7 over RHEL 6.5. In this article for some extra benchmarks to put out over the weekend is a quick comparison of Ubuntu 14.04 LTS in its current development state against Red Hat Enterprise Linux 7 Beta 1.

Fedora 19 vs. Fedora 20 Linux Benchmarks

Published today are benchmarks from two Intel systems comparing the performance of Fedora 19 "Schrödinger's Cat" to Fedora 20 "Heisenbug" for various workloads. Especially for those using open-source graphics drivers, Fedora 20 can be worth the upgrade for performance reasons.

FreeBSD 10.0 Kernel Comes To Debian

Advancing prudently but quietly within the Debian camp is the Debian GNU/kFreeBSD operating system that pairs Debian's GNU user-land with the FreeBSD kernel. For Debian 8.0 "Jessie" there are continued improvements on this spin that does away with the Linux kernel. Debian GNU/kFreeBSD Jessie/Sid currently defaults to the FreeBSD 9.2.0 kernel, but a FreeBSD 10.0 development kernel has already landed in Debian and is the focus of today's benchmarks.

Intel Linux Driver Almost Neck-And-Neck With Windows 8.1

Intel released a big Windows graphics driver update that for Haswell hardware now provides OpenGL 4.2 support -- while the Intel Linux driver just hit the milestone of OpenGL 3.3 support. To see how the latest Windows and Linux Intel graphics drivers compare, I ran some new benchmarks on Windows 8.1 against Ubuntu 13.10 to see how the performance pans out in various OpenGL game benchmarks and other graphics workloads.
