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.
The score using the kernel protocol stack is 548,400, while using Gazelle, it is 668,500, an improvement of over 20%.
In the 4k full-machine scenario, Gazelle improves performance by over 20%.
