- 4. The Basics
- 5. Use the latest PHP stable version Source: https://blog.asmallorange.com/2013/08/php-roadmap-performance/
- 6. Use the latest PHP stable version Source: https://www.lourdas.name/blog/php-53-vs-54-vs-55-speed-and-memory-usage Source: http://php.net/manual/en/features.gc.performance-considerations.php

- 10. Disable unnecessary PHP extensions 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 your php.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!
- 13. PHP ACCELERATORS
- 14. Alternative PHP Cache (APC) Zend OPcache XCache
- 17. ● Is PHP really your bottleneck? ● Same memory, less CPU ● Great for authenticated users. ● Some problems with NGINX (solvable!) ● Great resume: http://alexrayu.com/blog/drupal-hhvm
- 18. Scaling Drupal Horizontally (“Cattles, not Pets”)
- 19. Points of Attention ● Session ● Files ● Database ● Authenticated Users
- 20. Authenticated Users - AuthCache contrib 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. Use Drupal`s built-in Database API whenever possible! Avoid db_query(), always prefer specific functions.
- 22. And choose well your database!! ● MySQL ● MariaDB ● PerconaDB Version?!
- 25. How dependent of your actual environment are you? timezonepaths connection string limits timeouts Number of triesAPI Keys
- 27. Redis Specially useful for entities 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 Nginx Varnish
- 29. Some modules that break reverse 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”
- 31. Drupal Queue API
- 32. Helpful Modules
- 35. RULES! :-D
- 38. Profiling is about Measuring! XHProf
