Linux 4.0 SSD EXT4 / Btrfs / XFS / F2FS Benchmarks

A few days ago I ran some fresh hard drive file-system benchmarks on Linux 4.0 and today those results are being complemented by the solid-state drive results. Tested on the SSD were the popular EXT4, Btrfs, XFS, and F2FS file-systems.

Linux 4.0 Hard Drive Comparison With Six File-Systems

It's been a while since last running any Linux file-system tests on a hard drive considering all of the test systems around here are using solid-state storage and only a few systems commissioned in the Linux benchmarking test farm are using hard drives, but with Linux 4.0 around the corner, here's a six-way file-system comparison on Linux 4.0 with a HDD using EXT4, Btrfs, XFS, and even NTFS, NILFS2, and ReiserFS.

More Linux Benchmarks Of The AMD FX-8370E / FX-8370 / FX-9590

In adding some extra tests besides what was shared in our large Linux review of the new AMD FX CPUs from earlier in the week, that included a fairly big comparison of Intel and AMD CPUs, here's some more Linux test results for just the FX-8370E, FX-8370, and FX-9590 processors.

GCC 5.0 Outruns LLVM 3.5 Compiler By A Bit On Core-AVX2

In anticipation of the LLVM 3.5 release that brings a number of new compiler features -- including possible performance improvements from our benchmarking done earlier today -- here's some benchmarks comparing LLVM Clang 3.5 RC3 to a recent SVN snapshot of the GCC 5.0 compiler that's presently under development.

LLVM Clang 3.5 Brings Some Compiler Performance Improvements

If all goes well, LLVM 3.5 will be released today. While we have already delivered some LLVM/Clang benchmarks of the 3.5 SVN code, over the days ahead we will be delivering more benchmarks of the updated compiler stack -- including looking at its performance against the in-development GCC 5.0. For getting this latest series of compiler benchmarking at Phoronix started, here's some fresh numbers of LLVM Clang 3.4 compared to a recent release candidate of LLVM Clang 3.5.

Testing For The Latest Linux Kernel Power Regression

As I wrote about yesterday, there appears to be a new Linux kernel power regression that's yet to be solved by the latest Linux 3.17 code. The issue was originally tracked down to being a regression introduced during the Linux 3.15 stable cycle that disabled frame-buffer compression support by default for the Intel DRM graphics driver, but the impact it's had on the system power draw is much greater than what was anticipated by the Intel developers. A separate Intel employee is also reporting increased power draw, so I decided to run some tests on a few local systems to see what I'm encountering in the power consumption primarily between Linux 3.15 and 3.16.

CPUFreq Scaling Tests With AMD's Kaveri On Linux 3.16

In past months on Phoronix we have done many CPUfreq tests to see the impact of the different scaling governors and with Intel hardware how the CPUfreq driver compares to Intel P-State in terms of performance and power consumption. As we haven't done such ACPI CPUfreq tests on the AMD side in a long time, here's some benchmarks using a Kaveri APU and selecting the different scaling governors during performance benchmarking.

KVM Benchmarks On Ubuntu 14.10

For those wondering about the modern performance cost of using KVM on Ubuntu Linux for virtualizing a guest OS, here are some simple benchmarks comparing Ubuntu 14.10 in its current development stage with the Linux 3.16 versus running the same software stack while virtualized with KVM and using virt-manager.

Testing Btrfs On The Linux 3.16 Kernel

When running my initial Linux 3.16 file-system tests on an SSD I had to skip over Btrfs due to initial problems with the experimental kernel code. Fortunately, Btrfs has been fixed-up in Linux 3.16 and can now serve for some benchmarking.

Testing LLVM Clang 3.5's Code Generation Optimizations

For those curious about the performance of LLVM Clang in its current development form when testing the common code generation options for optimizing the performance (and in some cases size) of the resulting binaries, here's some fresh compiler benchmarks.

Intel Haswell HD Graphics Benchmarks With Linux 3.16

Phoronix benchmarks have shown that when using the Linux 3.16 kernel, the Nouveau performance is faster when taking advantage of the experimental re-clocking. Additionally, the Radeon graphics performance is faster on Linux 3.16 for newer graphics cards thanks to other optimizations. For Intel Haswell Linux users are there any performance improvements in store for Linux 3.16? Here's some tests.

Linux 3.16: Deadline I/O Scheduler Generally Leads With A SSD

There's been numerous requests lately for more disk I/O scheduler benchmarks on Phoronix of the Linux kernel and its various scheduler options. Given that there's routinely just speculation and miscommunication by individuals over the best scheduler for HDDs/SSDs, here's some fresh benchmarks for reference using the Linux 3.16 kernel.
