Optimizing WordPress - WordPress SF Meetup April 2012
The document discusses various levels of WordPress optimization. Level 1 focuses on keeping WordPress updated, using caching plugins like W3 Total Cache, deactivating unused plugins, and reviewing themes. Level 2 includes offloading images, feedburning RSS feeds, repairing the MySQL database, and using multiple subdomains. Level 3 suggests logging slow queries, profiling with tools, using a CDN, optimizing images, and using an opcode cache. Level 4 covers more advanced techniques like reverse proxying with Nginx, Varnish caching, Memcache, HyperDB, and static hosting on S3. The document advises against editing core files and notes that Amazon EC2 alone does not optimize performance.
