| Summary | 05771: ExprMgr_process_relevance_and_tailoring need more and more time after page reload | ||||
| Description | I have a problem regarding this survey: On the first pageload everythings seems to be okay (time "index.php": 484 ms) and the swithing between questions via mouseclick or tabs works well and fast. If I reload the page (Firefox: F5) it gets a bit slower. If I reload the complete page (STRG + F5) or load the page again (click on URL and Enter) it seems to sum up the time I have to wait. The problem child seems to be "ExprMgr_process_relevance_and_tailoring" which needs about 90% to 97% of the loading time. | ||||

Please upload the survey so I can test on my own. Take a look at the generated HTML. Although your page is only showing 4 questions, there is EM code for dozens of questions. The HTML is 17,000 lines long. |

|
Ah, must be a caching issue. The right amount of HTML is generated the first time. Each subsequent time, it re-generates the same tailoring code plus new tailoring code - so doubles in size with each page re-load. |

Uploaded the survey. |

Unfortunately, I can't reproduce the problem you're seeing. Every time I refresh the page using F5, I always get the same content. There is a function call LimeExpressionManager::StartProcessingPage()that clears the page-related cache every time it is called. It gets called every time you click next/previous/jump-to. It is also getting called every time I click F5 (looking at the stack trace, when I click F5, Firefox interprets that as a "movenext" command). Perhaps somehow it isn't on your configuration? I have Windows XP, Firefox 10, and am using XAMPP. Are you using ZEND or anything that might be caching your PHP sessions? Can you test this yourself (e.g. do you have access to XDebug or similar debuger so you can set a breakpoint within that function and try to figure out why it is being skipped when you press F5)? |

|
OK, I was able to reproduce this a different way - by using the Save/Resume feature. The problem is that sometimes EM calls GetLastMoveResult(), and it isn't properly clearing its cache, so content gets re-generated. |
