Jens Axboe, lead developer of IO_uring and Linux block maintainer, has introduced new Linux kernel patches aimed at significantly improving per-core I/O performance. This effort follows a presentation at last week's Linux storage, file-system, memory management and BPF summit (LSFMM) in Croatia, where Linux I/O overhead was compared to the Storage Performance Development Kit (SPDK). Motivated by these findings, Axboe's optimizations have achieved "around a 60% increase to the per-core I/O performance." These kernel-level enhancements are expected to boost the efficiency of I/O operations, particularly benefiting workloads sensitive to storage performance and concurrency.
