How is Apache APISIX Fast?

• apisix-benchmark

  2 1 0.0 Shell
  

Performance benchmarks (vs. Kong, Envoy) confirm these characteristics are indeed accurate (test yourself).

• lua-resty-ipmatcher

  1 119 1.6 Lua

  High-performance match IP address for Nginx + Lua

  

Under the hood, APISIX uses the lua-resty-ipmatcher library to implement this functionality. The example below shows how the library is used:

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• lua-resty-radixtree

  2 243 5.3 C

  Adaptive Radix Trees implemented in Lua / LuaJIT

  

APISIX uses the lua-resty-radixtree library, which wraps around rax, a radix tree implementation in C. This improves the performance compared to implementing the library in pure Lua.

• etcd

  61 46,345 9.9 Go

  Distributed reliable key-value store for the most critical data of a distributed system

  

APISIX uses etcd to store and synchronize configurations.

• rax

  2 1,084 0.0 C

  A radix tree implementation in ANSI C

APISIX uses the lua-resty-radixtree library, which wraps around rax, a radix tree implementation in C. This improves the performance compared to implementing the library in pure Lua.

• apisix

  63 13,652 9.6 Lua

  The Cloud-Native API Gateway

  

But the best part is that the libraries mentioned here and Apache APISIX are entirely open source, meaning you can look under the hood and modify things yourself.
