  • Wine-Staging 4.6 Brings Big Performance Improvement For Multi-Threaded Games / Apps

  • FOSSASIA OpenTech Summit’19

    Last month, I attended FOSSASIA’s annual conference which was held in Singapore. This conference was a collection of amazing, life-changing experiences. It was my first experience as a speaker and it taught me so much about the open-source culture. This summit took place from 14th March to 17th March in the beautiful city of Singapore. This was my second foreign trip as well. First one was to San Francisco as a part of the Student Startup Exposure Program.

    My flight was scheduled for 12th March from Jaipur and had a layover at Chennai for 5 hours. I reached the Changi Airport in the early morning of 13th. This airport was quite scenic and is also ranked as the top airport in the world.

  • OpenSUSE's Spectre Mitigation Approach Is One Of The Reasons For Its Slower Performance

    OpenSUSE defaults to IBRS for its Spectre Variant Two mitigations rather than the Retpolines approach and that is one of the reasons for the distribution's slower out-of-the-box performance compared to other Linux distributions. 

    A Phoronix reader pointed out this opensuse-factory mailing list thread citing a "huge single-core performance loss" on a Lenovo laptop when using openSUSE. There's a ~21% performance loss in single-threaded performance around the Spectre Variant Two mitigations, which itself isn't surprising as we've shown time and time again about the performance costs of the Spectre/Meltdown mitigations.
