Is SUPER Superior?

SUPER is a project to optimize SuSE for speed and performance. In looking for an idea for my next article, I thought this project's lastest effort might make an interesting review. It's based on OpenSuSE's latest release, which is 10.0 RC1. Being concerned with speed and performance, this review could not help but compare SUPER's times with that of OpenSuSE's. However, there was another kink in the armor. I'd already compared OpenSuSE with Mandriva. I got to thinking, was the test fair? Did they use the same boot options? Were the same services and deamons being started at boot? Did they both use parallel=yes? So, what started out as a review of SUPER has morphed into a speed test. Is Super really faster than other two contenders?

SUPER stands for SUSE Performance Enhanced Release. To quote the site: "SUPER is a testbed for anything that makes your SUSE Linux OS perform in a different manner than intended in the more stable and enterprise oriented SUSE Linux tree. This can be a speed improvement geared towards the specialized desktop user or an additional feature that is considered too experimental or dangerous by the main SUSE Linux tree." So, in other words they are trying to make a good thing even better by compiling base packages in a certain order, optimized per architecture (for dvd version), utilizing RUN_PARALLEL=yes, limiting boot time file operations, pre-linking and caching files for boot-up with readahead.

SUPER is quite scaled down in comparison to the OpenSuSE SuSE Linux distribution. Applications are limited in number, and in fact the entire distro comes on one cd and takes about 1.3 gig of hard drive space. As a result the menus are minimized as is the selection of applications. The full rpm list as tested is located here. One could set up an SuSE ftp mirror in yast and install whatever else they'd like I speculate. But otherwise it is almost identical on the surface to SuSE Linux 10.0 rc1.


    



But is SUPER superior in performance?


Given the fact that one needs to take into consideration the startup services, it's also important to note that Mandriva gives the user a choice during install and SuSE presumes to make that decision for us (although can be adjusted later). So, where at first consideration my original times (1, 2) may seem unequal, I submit perhaps they are. Another important note is that SuSE Linux runs RUN_PARALLEL=yes as well as preloads applications with readahead by default as found in SUPER.

For the sake of this rough and unscientific experiment, I installed on Reiserfs, used the same boot options, matched the start up services as closely as possible, booted to run level 3 with vga=normal. The clock is started when the <enter> key is depressed.

Discrepancies between this and previous tests may be contributed to booted run level, frame buffer, and having opened applications previously that boot. Represented below are the averages of 3 time tests for each area, first open of each application.

Firefox 1.0.6 1.0.6 1.0.6
gcc 4.0.1 4.0.2 4.0.2



As you can see, the optimizations in compiling methods of SUPER are having a significant performance increase once the system is booted, whether that was the compile order of the base system or the flags used in the individual applications. However, Mandriva is still smokin' 'em on the boot and shutdown times. There is no clear winner here, as it will depend on personal preference. If you are the type that has 3 month uptimes, you aren't going to care about boot times as much. On the other hand if you are the type that leaves your applications open just about from boot to boot, yet has to reboot to another os often, then application start times might seem less important. Is SUPER superior? It's up to you to decide.

New CloudBees Suite Addresses DevOps Gaps in Software Delivery

CloudBees is bringing a set of products into a new CloudBees Suite that it said will help companies of all sizes streamline the software development process. The new software is set to be announced Sept. 18 at the company’s DevOps World / Jenkins World conference in San Francisco. Jenkins is the open-source version of CloudBees, which is a commercial offering. A central piece of the CloudBees Suite is the CloudBees Core for unified governance of continuous delivery operations and processes used in DevOps. Software pipelines can also use Core to run software pipelines more efficiently in a self-managed way in the cloud or on-premises.

Mozilla: Firefox Lockbox, Project DeepSpeech, Firefox Reality, Servo

  • AutoFill your passwords with Firefox Lockbox in iOS
    Today Firefox Lockbox 1.3 gives you the ability to automatically fill your username and password into apps and websites. This is available to anyone running the latest iOS 12 operating system.
  • Streaming RNNs in TensorFlow
    The Machine Learning team at Mozilla Research continues to work on an automatic speech recognition engine as part of Project DeepSpeech, which aims to make speech technologies and trained models openly available to developers. We’re hard at work improving performance and ease-of-use for our open source speech-to-text engine. The upcoming 0.2 release will include a much-requested feature: the ability to do speech recognition live, as the audio is being recorded. This blog post describes how we changed the STT engine’s architecture to allow for this, achieving real-time transcription performance. Soon, you’ll be able to transcribe audio at least as fast as it’s coming in.
  • Explore the immersive web with Firefox Reality. Now available for Viveport, Oculus, and Daydream
    Earlier this year, we shared that we are building a completely new browser called Firefox Reality. The mixed reality team at Mozilla set out to build a web browser that has been designed from the ground up to work on stand-alone virtual and augmented reality (or mixed reality) headsets. Today, we are pleased to announce that the first release of Firefox Reality is available in the Viveport, Oculus, and Daydream app stores. At a time when people are questioning the impact of technology on their lives and looking for leadership from independent organizations like Mozilla, Firefox Reality brings to the 3D web and immersive content experiences the level of ease of use, choice, control and privacy they’ve come to expect from Firefox. But for us, the ability to enjoy the 2D web is just table stakes for a VR browser. We built Firefox Reality to move seamlessly between the 2D web and the immersive web.
