The last time we ran a performance comparison of different Linux distributions on netbooks was in late November, but now we have a new set of Linux distributions out there, so we have carried out a new comparison. In particular, we are looking closely at how the MeeGo distribution --

The newest Linux kernel release continues its rapid development pace, adding a pair of new filesystems and boosting virtualization performance.

Last weekend a few Phoronix benchmarks were underway of the Linux 2.6.32-rc5 kernel when a very significant performance regression was spotted. This regression caused the PostgreSQL server to run at about 18% of the performance found in earlier kernel releases.

NexusWare v12 is built on the 2.6.20 Linux kernel and conforms to OpenHPI, an open source implementation of the Service Availability Forum's hardware platform interface. It is one of the only Linux distributions to be Carrier Grade Linux 3.2-registered, meeting a set of essential Linux capabilities for performance, high availability, security and reliability.

Out of the box, Linux runs just fine for many uses. But if you find yourself needing to ferret out performance problems or tune the kernel for better performance, Linux has more than enough tools to measure and tweak system performance.

If you are using nginx as your webserver, you are looking for a performance boost and better speed. nginx is fast by default, but you can optimize its performance and the performance of all parts (like PHP and MySQL) that work together with nginx. Here is a small, incomprehensive list of tips and tricks to configure your LEMP system (Linux, nginx, MySQL, PHP-FPM) for maximum performance.

After a Thanksgiving break, the Whirlwind Tech Tour is back on the move. This week, we address the issue of how Linux distributions compare in performance under different enterprise conditions.

Since we began benchmarking Btrfs a few months ago we have found it to not deliver any spectacular file-system performance results on Linux. Committed to the Linux 2.6.31 kernel was Btrfs v0.19. Does this release bring any performance improvements? Yes and no.

As was mentioned in last Friday's article, Which Is Faster: Debian Linux or FreeBSD, tests of FreeBSD atop the ZFS file-system (rather than UFS2+S) are currently underway and those results are expected to be published in full later this week as the ZFS disk performance is compared directly to UFS2+S, UFS2+J, and also Ubuntu Linux with the EXT4 and Btrfs file-systems.
