Transcript

1. React PHP & Symfony by @acasademont Symfony Catalunya 2016
2. about me Albert Casademont software engineer @ ulabox.com @acasademont finishing my MBA () really obsessed with performance!!
3. performance
5. the life of a PHP request 1. parsing 2. AST (Abstract Syntax Tree) 3. bytecode 4. execution
7. opcache to the rescue
8. the life of a PHP request 1. parsing 2. AST (Abstract Syntax Tree) 3. bytecode 4.execution
9. set up opcache NOW!! (please )
10. the life of a PHP request 1. parsing 2. AST (Abstract Syntax Tree) 3. bytecode 4.execution
12. NOT BAD!!
13. set up PHP7 NOW!! (please )
15. 40ms not fast enough!
16. WTF!
17. the life of a PHP request 1. parsing 2. AST (Abstract Syntax Tree) 3. bytecode 4.execution
18. PHP execution time • initialization!!! memory allocation => composer, DI… • useful execution
19. aren’t we wasting A LOT of resources?
20. YES so…what else?
22. React PHP •reactor pattern, event loop •NodeJS style! •CLI PHP process •acts as an http server •===> globals persist! <====
23. PHP-PM •acts as a process manager on top of React-php •also written in plain PHP •Much like PHP-FPM, but no fcgi
24. show time!
25. so…is it fast/er?
26. test environment •1 VB, single core, 1GB RAM •ulabox.com website •Full Symfony 2.8.8, prod env •PHP-FPM: opcache, 5 workers •PHP-PM: no-opcache, 5 workers
27. 0 10 20 30 40 median request time (ms) React FPM 0 20 40 60 80 100 requests per second React FPM
28. ~35-40% faster
30. important caveats •globals globals globals! •debugging becomes weird •Careful with Doctrine! •memory leaks •not production ready, still buggy
31. the future •still work to do! •a whole new async world! •future default PHP app server? •it’s written in PHP => explore!!
32. resources! •github.com/reactphp •github.com/php-pm
33. questions?
34. gràcies ;) we are hiring!
