Thank you very much.</p> <p> Martin</p> <p>This time is spended creating and invoking change events on listeners, newer faster API is available in Lithium for Data Change Listeners.</p> <p>25% of CPU time, during ten invocations is not bad, if you are doing profiling,<br/> please monitor controller for longer period and use larger data sets, large burst operations to distinguish normal operations from sub-par performant ones.</p> <p>The fix is to switch to DataTreeChangeListener &#8211; there is nothing we can optimize on DataChangeListeners, unfortunately.</p> Development External issue ID 4076 External issue URL Rank 0|i02qbr:
