2. WHAT IS SWOOLE?
3. INTRODUCTION Swoole is a PHP extension, high-performance network framework based on an event-driven, asynchronous, non-blocking I/O coroutine programming model for PHP.
4. CONCURRENCY & PARALLELISM
5. USING MULTI THREADS/PROCESSES 5 Why we can't just spawn threads and fork processes if run programs in parallel are faster?
6. 6 • Race Conditions • Mutex • Deadlock • Debugging & Testing • Memory Overhead Why we can't just spawn threads and fork processes if run programs in parallel are faster? USING MULTI THREADS/PROCESSES
7. 7 EVERYTHING IS ABOUT TRADE-OFFS Sometimes, forking processes worth, for example: Browsers.
8. HOW TO SOLVE THIS PROBLEM? 8
9. 9 WHAT IS I/O? • Database - ( Connection, Queries ) • Sockets - ( TCP/UDP ) • File System - ( Read/Write ) • Unix Sockets
10. BLOCKING I/O 10
11. HOW TO MAKE I/O NON-BLOCKING? 11
12. I/O MULTIPLEXING & EVENT LOOP 12
13. FILE DESCRIPTORS 13 File descriptors are numerical identifiers used by operating systems to represent input/output (I/O) resources.

17. 17 Comparing with PHP-FPM
18. CONCLUSION 18 • Swoole uses a concurrency model in order to increase our PHP performance, using non-blocking I/O. • Parallelism is actually faster but it triggers several problems. • Concurrency tries to find a balance between performance and memory/processing consumption. • Swoole can be used instead of PHP-FPM, having their own trade-offs.
