In collaboration with Emmanuel Cohen. At a key moment for online press in France, a major French news company chooses PHP and Symfony to extend its popular web site. We will present the architecture we designed at Sensio Labs to meet a very good performance requirement. We used Symfony2 kernel wrapping symfony 1.4 and relied on loose-coupled applications serving content from heterogeneous backend sources.

Nice performance using Sf2 cache wrapping Sf1 application - Paris
- 1. Nice performance using SF2 cache wrapping sf1 application Marc Weistroff Emmanuel Cohen Sf Live SF 2011 Thursday, March 3 2011
- 14. How does this app work ?
- 17. Addressing performance with Symfony2
- 25. ESI : A page in lexpress.fr
- 28. How does ESI work?
- 30. /movie/dogma
- 31. /movie/dogma
- 34. First request ever Client Proxy Application /movie/dogma /movie/dogma miss Cache-Control: s-maxage=600 /movie/dogma/casting /movie/dogma/critics Cache-Control: s-maxage=3600 Cache-Control: s-maxage=300
- 35. Request at t+200 Client Proxy Application /movie/dogma hit
- 36. The application is never hit! As if the complete page was cached in the reverse proxy
- 37. Request at t+500 Client Proxy Application /movie/dogma /movie/dogma/critics Cache-Control: s-maxage=300 hit
- 38. The application is partially hit And has to build only a small fragment of the page
- 41. But our app is symfony 1 right ?
- 44. Wrapping symfony 1 with Symfony2
- 46. symfony 1 needs tweaking in order to work around a few obstacles
- 51. Final app architecture EsiCacheKernel SymfonyWrapperKernel symfony 1 application
- 53. Then… You have to design your app to serve HTML fragments!
- 55. And now where happy
- 56. Or are we ?
- 58. This is symfony1 : DO NOT TRY ANY OF THIS AT HOME!
- 60. What to do next ?
- 62. Proxy ESI New response Or 304 URL-> {ETag} ETag-> lastmodified If Etag absent or stale Response with HTTP headers Etag LastModified Client Request with HTTP headers If-None-Match If-Modified-Since App New response Or 304 If cache entry is not fresh enough Cache Validation Optimizer
