I created a report, chose the accelerated report option and selected a 7 day time range.
One of the panel is referring to the accelerated reports in the source code this way:
<row>
<panel>
<title>Accelerated report - test</title>
<chart>
<search id="BaseSearch" ref="NbOfEventsByEventType">
<earliest>$field1.earliest$</earliest>
<latest>$field1.latest$</latest>
</search>
<option name="charting.chart">column</option>
<option name="charting.drilldown">none</option>
</chart>
</panel>
</row>
I made a panel below this one (an another one in a different dashboard to make sure there was no overlapping at all), with the search being the original query instead of a ref to the accelerated report. I then choose with a dropdown a time range of the last 7 days, which starts the update of both panels. Their searches are done at the same time (and thus display the chart at the same time).
Why does the ref to the accelerated reports has no effect on the performance of the panel?
