Changes and New Features in this Version

Feature/Category

Description

XLIO Multithreaded Applications Optimization in Worker Threads Mode

Added Passthrough support in XLIO Worker Threads mode (see Worker Threads Mode). Passthrough is a mechanism by which XLIO falls back to the kernel network stack for sockets and traffic that cannot or should not be accelerated. 

XLIO OOB Experience Enhancement with Dynamic and AI-Driven Configuration 

Added XLIO configuration and tuning report references, including a complete runtime parameter guide and diagnostic report guidance to help customers understand generated reports, identify performance bottlenecks, and tune XLIO configuration.

For more information, see XLIO Tuning Report

Important Notes

As of XLIO v3.10, DEBUG-level logs will not be available in the release builds. Alternatively, you can use libxlio-debug.so to obtain those logs. For details on how to use libxlio-debug.so, please refer to Libxlio-debug.so section.

libnl1 is no longer supported. Please use libnl3 instead.
