So here are my thoughts about what would be good for the beginner to consider when he starts with PHP performance optimizations. Note that I do not say it's the only thing you should do '" there are a bunch of articles, talks, blogs, etc. about PHP performance and many of them contain very good advice and go into much more details than I intend to go into.
Suggestions on his list include:
- Bytecode cache
- Don't try to outsmart the engine
- Leverage the extensions
- Use php.ini-production as a start
