The NVIDIA® Accelerated IO (XLIO) SW library boosts the performance of TCP/IP applications based on NGINX (CDN, DoH Etc.) and storage solutions as part of the SPDK. XLIO is a user-space software library that exposes standard socket APIs with kernel-bypass architecture, enabling a hardware-based direct copy between an application’s user-space memory and the network interface. 

Coupling XLIO with NVIDIA ConnectX®-6 Dx and NVIDIA ConnectX®-7 acceleration capabilities provides breakthrough performance of Transport Layer Security (TLS) encryption/decryption. It also enables working with features such as HW LRO/TSO and Striding-RQ which increase TCP performance, without application code changes and using a standard socket API.

XLIO is an open source project - see its repository here.
