3. What is Swoole?
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 FPM Pool FPM Pool Worker Worker Worker Worker Blocking I/O
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 Queue PubNub
 Service Analysis Service Swoole Service PubSub Many to Many Queue Workers High Concurrent Requests
31. Use Case • Replace Guzzle Handler with Swoole Client
