Kunai vs io_uring
· 7 min read
Introduction
io_uring is a cutting-edge feature in the Linux kernel since version 5.1, revolutionizing input/output (I/O) operations through asynchronous processing. By using shared ring buffers between user space and the kernel, it minimizes system calls and context switches, significantly reducing latency and improving throughput. This makes it ideal for high-performance applications like databases, web servers, and real-time data processing systems. With support for a wide range of I/O operations and flexible polling mechanisms, io_uring offers unparalleled efficiency and scalability.
In this blog post, we explore how io_uring works, its security implications, and how tools like Kunai can monitor io_uring operations.
