This document summarizes Mitch Pirtle's presentation on Joomla! extreme performance. The presentation covered assessing performance from all aspects including server output, network throughput, and browser footprint. It provided tips on establishing a performance baseline, optimizing server output through caching and tuning, improving network throughput with gzipping and CDNs, and reducing browser footprint by consolidating assets and removing inline styling. It also addressed scaling issues and tools for debugging performance problems.

16. What is performance?

17. Performance != Scale

19. Performance:
How fast can the page load?

20. Performance:

50. What’s a Developer to do?

51. Developer Checklist
You’re using all the framework classes instead of
crappy, homegrown code right?
Are your extensions really using JCache properly?
Are you running explain plans on your SQL statements
and checking for index and lock contention?
You’re using MySQL’s slow query log, right?

52. Distributed Systems Issues
Hard to push code updates
Hard to keep data consistent
Hard to debug issues
Additional effort to development
Limits options of existing extensions and services
