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
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!

● 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
Scaling DrupalHorizontally
(“Cattles, not Pets”)
Points of Attention
● Session
● Files
● Database
● Authenticated Users
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
Avoid database specific queries.
Use Drupal`s built-in Database API whenever possible!
Avoid db_query(), always prefer specific functions.
And choose wellyour database!!
● MySQL● MariaDB● PerconaDB
Version?!
How dependent of your actual environment are you?
timezonepaths connection stringlimits
timeouts
Number of triesAPI Keys
Caching Mechanisms
RedisSpecially useful for entities
Memcachefor key/value storageURI -> HTML output, Session data
tmpfs/ramfsfor all filesystem (I/O intensive) based caching like Boost.
Use Drupal’s built-in
Cache API
Reverse proxy caching
Nginx Varnish
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”
Drupal Queue API
Helpful Modules
