title: Performance Instrumentation
|
|
type: text/vnd.tiddlywiki
|
|
|
|
The core has built-in performance instrumentation for the refresh cycle. See “Performance Instrumentation” on the “Settings” tab of control panel. The wiki will need to be reloaded before it takes effect.
|
|
|
|
With performance instrumentation switched on, there is additional timing information displayed the browser developer console each time a refresh cycle is triggered. For example:
|
|
|
|
```
|
|
performance: mainRender: 327.83ms
|
|
performance: styleRefresh: 9.14ms
|
|
performance: mainRefresh: 68.10ms
|
|
```
|
|
|
|
The information above should be interpreted as follows:
|
|
|
|
* mainRender is the time taken for the initial display of the page template
|
|
* styleRefresh is the time taken to refresh the page stylesheet
|
|
* mainRender is the time taken to refresh the main page template
|
|
|
|
As an example, try switching between the sidebar tabs to compare how long they take to render.
|
|
|
|
More detailed information on filter execution timings is also available. With performance instrumentation enabled, type the following JavaScript command in the browser developer console:
|
|
|
|
```
|
|
$tw.perf.log()
|
|
```
|
|
|
|
A table is displayed with the following information:
|
|
|
|
* ''name'' - the string "Filter: " plus the text of the filter
|
|
* ''invocations'' - the number of invocations of the filter since startup
|
|
* ''totalTime'' - the total time in milliseconds spent evaluating this filter since startup
|
|
* ''percentTime'' - the percentage of the execution time of this filter against the total execution time of all filters
