3. What is Swoole?

4. None

5. What is Swoole? • A C extension for PHP •

   An asynchronous network engine for PHP • Features: • Event-driven non-blocking I/O • HTTP / HTTP2 / Websocket / TCP / UDP • Coroutine (CSP Model) • High performance for high concurrency

6. Why PHP Performs Poorly in High Concurrency?

7. Lifecycle in PHP

8. Lifecycle in PHP PHP

9. Blocking I/O in PHP Request Request Request Request PHP FPM

10. Eventloop in NodeJS

11. There’s no Eventloop in Traditional PHP

12. Let’s See What Changes in Swoole?

13. Structure in Swoole Server

14. Structure in Swoole Server • Code Is Persistent in Memory

    • Swoole Takes Lifecycle Over PHP • Reduce Initialization Steps • Reduce Response Latency • Event-driven Non-blocking I/O for Requests

15. Benchmark Comparison of Go with Swoole

16. Server Benchmark in Go

17. Server Benchmark in Go

18. Server Benchmark in Swoole

19. Server Benchmark in Swoole

20. This Doesn’t Mean PHP with Swoole is Faster Than Go

    (Of Course Not)

21. Coroutine in Swoole

22. Coroutine in Swoole • Blocking I/Os Are Scheduled By Coroutine

    Automatically.

23. Coroutine in Swoole • Blocking I/Os Are Scheduled By Coroutine

    Automatically.

24. Coroutine in Swoole • CSP Model

25. Does This Mean Every Blocking I/O Doesn’t Block Anymore?

26. Coroutine in Swoole • How about This?

27. Coroutine in Swoole • How about This?

28. Runtime Hooks Transform Blocking I/Os into Coroutines with Magic!

29. Use Case In HandsUp

30. Use Case Facebook Webhooks Message Load Balancer Server Server Server

 Service Analysis Service Swoole Service PubSub Many to Many Queue Workers High Concurrent Requests

31. Use Case • Replace Guzzle Handler with Swoole Client
