<p class="MsoNormal"><span lang="EN-US"><a href="https://gitee.com/openeuler/gazelle">gazelle</a> is a high-performance user-space protocol stack based on DPDK. It has been open-sourced in the openEuler community and released with the openEuler LTS version.
Thanks to DPDK's high-performance packet processing and gazelle's efforts in scheduling, threadization of the protocol stack, etc., gazelle has strong competitiveness in terms of latency, throughput, etc. It can achieve a performance improvement of 20%+ for
MySQL and 100% for Redis. Currently, it is widely used in scenarios such as finance and storage.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">We have noticed that the DPDK community encourages everyone to
<a href="https://www.dpdk.org/ecosystem/">build open-source projects based on DPDK</a>. We also hope to interact with the DPDK community and leverage the power of the community to make gazelle better. Therefore, we hereby apply to join the DPDK open-source
project ecosystem. We hope to strengthen our connection with the community, grow together with the community, and contribute to the prosperity of the DPDK community ecosystem. We look forward to your reply.<o:p></o:p></span></p>
