EnhanceIO, Bcache & DM-Cache Benchmarked

Three different Linux disk caching methods for the Linux kernel were compared: EnhanceIO, Bcache, and DM-Cache. But which of these disk caching methods is the fastest when mixing SSDs and HDDs? Here's some results.

Linux's "Ondemand" Governor Is No Longer Fit

By default the Linux kernel uses the "ondemand" CPU frequency governor for achieving maximum clock frequency when system load is high and a lower clock frequency when the system is idle. However, it turns out that for at least modern Intel CPUs, this is likely no longer the case. This default kernel choice may lead to poor battery life and performance for modern Linux systems.

Linux 3.10 Kernel Yields Biggest Changes In Years

The Linux 3.10 kernel is going to be massive with the just-released "-rc1" version being the biggest in the last several years (or perhaps ever), according to Linus Torvalds. This massive change-rate is based at least according to commit count and potentially actual lines too.

Linux 3.10 Kernel Integrates BCache HDD/SSD Caching

After being in development for more than one year, BCache was finally merged on Wednesday into the mainline Linux kernel code-base. BCache serves as an SSD caching framework for Linux by offering write-through and write-back caching through a newly-exposed block device.

Tux3 File-System Claims To Be Faster Than Tmpfs

The experimental Tux3 file-system has already made claims of being faster than EXT4. The latest claims out of the open-source file-system is that it's faster than Tmpfs, which is quite a feat given its very thin layer between VFS and SWAP.

Full DynTicks Proposed For Linux Kernel Integration

Aside from the KVM pull request, another interesting proposed change for the Linux 3.10 kernel is the "full dynticks" support, also known as CONFIG_NO_HZ_FULL. Ingo Molnar is trying to get this brand new feature into the next Linux kernel release.

Linux 3.10 Gets New ARM, AMD Power Improvements

Along with an assortment of other power management improvements to land with the Linux 3.10 kernel, a cpufreq driver for ARM's big.LITTLE is being introduced. There's also a cpufreq driver for the Exynos 5440 quad-core and the new AMD frequency sensitivity feedback support.
