Escalando php e drupal- performance ao infinito e além! - Drupal camp sp 2015
This document discusses strategies for scaling PHP and Drupal applications. It recommends using the latest stable version of PHP and disabling unnecessary PHP extensions and modules to improve performance. It also discusses tuning PHP settings like memory limits and caches. For Drupal, it suggests using caching, database optimizations like read replicas, and balancing load across multiple servers. Profiling tools can help identify bottlenecks.

- 10. Disable unnecessary PHPextensions and web-server modules ● PHP extensions consume memory heap ● Some badly written can cause memory leaks ● The same applies for web-server modules ● Disable if you don’t need them! 2Read: http://www.slideshare.net/jpauli/help-im-leaking-memory-in-php
- 11. Fine tune yourphp.ini! ● memory_limit memory_get_usage() / memory_get_peak_usage() ● realpath_cache_size realpath_cache_get() ● realpath_cache_ttl Max execution per thread - will affect memory usage!

- 19. Points of Attention ●Session ● Files ● Database ● Authenticated Users
- 20. Authenticated Users - AuthCachecontrib module - Memcache - AJAX Database - MySQL Read Replicas + AutoSlave contrib module + Orbital Cache Nuke (OCN) Files - Rsync bi-directional replication - NFS shared mount - Cloud-based solution (S3/GCS) Session - Drupal handes it beautifully - Session is stored on Database - Memcache to cache tables
- 21. Avoid database specific queries. UseDrupal`s built-in Database API whenever possible! Avoid db_query(), always prefer specific functions.
- 22. And choose well yourdatabase!! ● MySQL ● MariaDB ● PerconaDB Version?!
- 25. How dependent ofyour actual environment are you? timezonepaths connection string limits timeouts Number of triesAPI Keys

- 27. Redis Specially useful forentities Memcache for key/value storage URI -> HTML output, Session data tmpfs/ramfs for all filesystem (I/O intensive) based caching like Boost. Use Drupal’s built-in Cache API
- 28. Reverse proxy caching NginxVarnish
- 29. Some modules that breakreverse caching Adaptive Image - Since it detects browser to serve image the reverse proxy will cache the first occurence. Text Size - Use cookies to store user choosen size. Recaptcha - Use cookie to store valid challenge. Key phrases: “Depends on cookies” “Browser detection”
