Editor's Notes
- #9 Websites have more pages than you think. Performance effects are aggregate.
- #12 Database Buffer Cache Network etc
- #18 Overloaded databases Badly configured machines NFS / File system contention Solutions: Get a real system administrator Pick the right database for the job Clustered / Proxy databases
- #19 Missing indexes. Poor schema architecture. Bad database tuning. Selecting too many columns / rows
- #20 Proxy callout to external services Remote PHP includes REST / AJAX SOAP / RPC calls Solutions: Cache the network calls Design your AJAX so you can easily cache it
- #21 Image manipulation Encryption system/exec/etc. function calls Solutions Off load work to other machines Gearman and similar are your friends
- #22 Performing extensive looping text replacements Performing extensive looping in general Badly written Regular Expressions Extensive recursive functionality
