nr_perfanalysis is a TYPO3 extension that collects and displays
frontend rendering timing and quantity information.
It displays the summary at the bottom right of the frontend pages:
TYPO3 introduction package rendering with nr_perfanalysis output
Contents
By enabling the extension, the frontend performance bar is automatically shown whenever a TYPO3 page is generated.
Clicking on the bar hides it.
The reload button will do a "document.location.reload(true)" which will override the browser cache.
Hovering over the button shows the current document.location (helpful on devices that don't display a URL bar).
it is possible to enable the analysis but displaying the result in the frontend only if you have a specific cookie set.
In the extenion manager you can enable the option Require cookie for displaying result in frontend (Cookie nr_perfanalysis=1 needs to be set)
If this option is active the result will only be displayed if the current request
has the cookie nr_perfanalysis=1 set.
page- Server-side page rendering time
sql- SQL query count and time
browser- Browser rendering time
Your own extensions can collect statistical data, too.
Start an event:
$statCounter = Netresearch\NrPerfanalysis\Counter::get();
$statCounter->start('REST', 'PUT');
Finish it off:
$statCounter = Netresearch\NrPerfanalysis\Counter::get();
$statCounter->finish('REST', 'PUT');
Now you logged a "PUT" event in the "REST" group, and the REST group will show up in the statistics on the bottom right.
- TYPO3 6.2+
- PHP 5.4+ for page generation statistics
nr_perfanalysis is licensed under the AGPL v3 or later.
