LAVD scheduler: from games to servers with BPF

What happened and what to do

According to the LWN article on the Kernel Recipes 2026 talk by Changwoo Min and Gavin Guo, the LAVD scheduler was originally created for games and now serves other types of workload. The article highlights that the extensible scheduler class, which allows custom CPU schedulers to be built with BPF, sparked a wave of innovation in the area, and that LAVD is one of the most notable examples. The talk gave an overview of the scheduler and how it evolved over time.

For a company running inference servers, APIs or data processing, the practical lesson is that CPU scheduling can be tuned to the real load rather than relying only on the operating system default. A possible initiative is to measure tail latency and CPU usage per task type in test environments, compare the default scheduler with BPF-based alternatives, and only then decide whether the change pays off. Any change to a production kernel requires regression testing, a planned rollback and continuous monitoring.

How the consultancy can help

Diagnosis of how your infrastructure workload behaves under the current scheduler, with latency and CPU usage measured per task type. Then design and implementation of a controlled test environment to evaluate BPF-based extensible schedulers, with a rollback plan and monitoring on your own infrastructure.

Next step

If your company runs servers with mixed workloads and wants to assess whether scheduling adjustments bring real gains, send a short description of your scenario, the type of workload and the performance signals you observe. From it, Wendelmaques prepares a scoped proposal with diagnosis and implementation steps.
