Intel's Clear Linux Distribution Offers Fast Out-Of-The-Box Performance (phoronix.com)

Posted by timothy on from the new-to-me dept.

An anonymous reader writes: In a 10-way Linux distribution battle including OpenSUSE, Debian, Ubuntu, Fedora, and others, one of the fastest out-of-the-box performers was a surprising contender: Intel's Clear Linux Project that's still in its infancy. Clear Linux ships in an optimized form for delivering best performance on x86 hardware with enabling many compiler optimizations by default, highly-tuned software bundles, function multi-versioning for the most performant code functions based upon CPU, AutoFDO for automated feedback-direct optimizations and other performance-driven features. Clear Linux is a rolling-release-inspired distribution that issues new versions a few times a day and is up to version 5700.

    Intel's own compiler in many cases generated code that runs 15%-20% faster than code compiled under GCC.

      TFA says that GCC was used, not ICC.

      A few years back, GCC took out all the processor-specific optimizations and put in only general purpose optimizations. That made it less efficient, so I can believe putting back in all the processor-specific stuff would make it run 15% to 20% faster. I also suspect the Intel Linux Distro is extremely limited as to what hardware it runs on, but that's the tradeoff you make for maximum optimization.

      Clear Linux also comes packaged with spyware

      From the 1st paragraph at that link:

      The end users may disable the telemetry component of Clear Linux OS for Intel Architecture or even redirect where records go if they wish to collect for themselves.

  2. Telemetry by Anonymous Coward · · Score: 2, Informative

    "In support of the goal to provide an agile Linux* distribution that rapidly detects and responds to quality issues in the field, Clear Linux for Intel® Architecture includes a telemetry solution, which notes events of interest and reports them back to the development team."
