Reduce System Call Overhead for Event-Driven Servers

Explore strategies to optimize event-driven server performance by minimizing system call overhead in this 32-minute Linux Foundation conference talk. Delve into various IO models, including nonblocking asynchronous and synchronous approaches, and compare Pulse IO with Linux IO. Examine the implementation details, performance results, and limitations of different techniques. Learn about the impact of payload size, loading latency, and radius on server efficiency. Gain insights into error handling, IOPS, and the executing path of IO operations. Understand the role of IORing and discover how to leverage these concepts to enhance server responsiveness and throughput in event-driven architectures.
