Konstantin has been a FreeBSD committer since 2006, and he recently implemented support for current-generation Intel graphics controllers under contract to the FreeBSD Foundation. This new position will allow him to spend his full working time on supporting and improving FreeBSD.
Konstantin’s first project brings support for unmapped I/O to FreeBSD. The unmapped I/O project improves performance by avoiding mapping buffers in the buffer cache, significantly reducing overhead on multi-processor systems. The project builds on foundational work to unify machine-dependent parts of the busdma interface, recently contributed by Jeff Robertson at EMC’s Isilon Storage Division. EMC became a FreeBSD foundation donor in 2012.
Netflix, another new Foundation donor for 2012, is already making use of this project.
“Netflix partnered closely with Konstantin to provide design input and testing resources for the unmapped I/O project. The work helped us realize an immediate 25% increase in system performance on production workloads. It underscores the immense value of collaborating and investing in the open source community and FreeBSD in particular,”
said Scott Long, Senior Software Engineer at Netflix.
Konstantin has also been working with the release engineering team since 2008 and his new role with the Foundation will allow him to focus more time on the tools and process used to make FreeBSD releases. (via)
