This talk will delve deep into the innovative use of threads versus fibers in user-space cooperative scheduling, drawing upon real-world applications in the context of planet-scale storage systems, particularly Google Cloud Storage.
This talk will explore how Google Cloud Storage leverages fibers to address the challenge of "noisy neighbors" – non-conformant clients that can monopolize resources and degrade performance for others. By employing fibers and user-space cooperative scheduling, GCS achieves fairer CPU resource allocation, prioritizing conformant clients while strategically throttling non-conformant ones.

During this session, I will explore the architectural considerations and performance trade-offs between threads and fibers, leveraging my experiences from leading this project at Google.
This talk will be particularly beneficial for engineers and architects involved in building or maintaining large-scale distributed systems.
