Intel has published a series of fixes for Linux aimed at improving the performance of modern Alder Lake processors and those CPUs that will follow them.


Alder Lake is known to have a mix of large and small cores, and the performance of such CPUs is highly dependent on optimization. That’s what new fixes were released for. They configure the Linux kernel scheduler, including preventing unnecessary migrations in SMT domains.

It is expected that after these fixes, the energy-efficient cores of new processors will be able to more actively take over tasks from large cores. Unfortunately, there are no comparative tests yet.
