Presenting high performance photo gallery

4. Freelancing and building open-source software in free time

7. Unoptimized SQL query's

8. Resource hungry

9. No framework used (well, perhaps this is not a problem, but most of the time they just duplicate frameworks functionality, reinventing the wheel...)

10. No Etag based caching, bandwidth saver...

12. Fulltext search engine

13. Etag based caching

14. SQL querys caching

15. Fullpage caching

16. Low resource requirements

18. Sphinx – free open-source SQL full-text search engine (http://sphinxsearch.com/)

19. Memcached – free & open source, high-performance, distributed memory object caching system (http://memcached.org/)

20. eZ Components – an enterprise-ready, general-purpose PHP library of components used independently or together for PHP application development. (http://ez.no/ezcomponents)

21. JQuery – is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. (http://jquery.com/)

22. Lighttpd – lightweight open-source web server. (http://www.lighttpd.net/)

23. Mysql – database engine (http://www.mysql.com)

25. Configuration

26. Database

27. Feed

28. ImageAnalysis

29. ImageConversion

30. PersistentObject

31. Translation

32. Cache

33. Url

34. UserInput

45. Not a single slow query

47. SELECT * FROM `lh_gallery_images`

48. INNER JOIN ( SELECT pid FROM lh_gallery_images ORDER BY comtime DESC, pid DESC LIMIT 20 OFFSET 20 ) AS items

49. ON lh_gallery_images.pid = items.pid

50. This query is at least 5x times faster than normal select. Tested with (150 K records.)

65. User ID is needed if user is logged in.

66. Can be used for custom pages, that do not change

67. Then image is uploaded or deleted, we just increase cache version and Etag is expired automatic also.

69. Mysql queries

71. Traffic stats

73. No performance issues at this time.
