User-Space Protocol Stack Gazelle

Introduction

Gazelle is a high-performance user-space protocol stack. It is based on DPDK for directly reading and writing network packets in user space, sharing large-page memory to transmit packets, and using the lightweight LwIP protocol stack. It significantly improves the network I/O throughput of applications, focusing on accelerating database network performance, such as MySQL and Redis, while balancing high performance and generality:

High Performance
Zero-copy packet processing, lock-free, flexible scale-out, adaptive scheduling.
Generality
Fully POSIX-compatible, no modifications required, suitable for different types of applications.

Performance Results

MySQL 8.0.20

The score using the kernel protocol stack is 548,400, while using Gazelle, it is 668,500, an improvement of over 20%.

Ceph 14.2.8

In the 4k full-machine scenario, Gazelle improves performance by over 20%.
