Timeline graphs causing slowness even when they are not been displayed

[robertlynch2020]

Hi

The below panel is only used 1% of the time, however it is causing my dashboard to be very very slow even when it is not displaying.

The tstat is quick in a search, however $GANTT_CHART_ON$ is off most of the time, but the whole dashboard is slow, i don't mind it been slow when i want to see the "timeline" Graph, but it is like it is drawing it when i don't want to see it. As a result i am getting 10 seconds hangs.

<panel depends="$TPS_ON_OFF$,$TPS_ON_ALL_PANELLS$,$GANTT_CHART_ON$">
      <title>TPS Real-Time Activity Gantt Chart: = $TPS_Class_token$</title>
      <viz type="timeline_app.timeline">
        <search>
          <query>| tstats summariesonly=$summariesonly_token$ max(All_TPS_Logs.duration) AS All_TPS_Logs.duration FROM datamodel=MLC_TPS_DEBUG4 WHERE (nodename=All_TPS_Logs host=$host_token$) All_TPS_Logs.name =*$TPS_Class_token$* GROUPBY _time, All_TPS_Logs.$fullyQualifiedMethod_or_class$ span=1s | rename All_TPS_Logs.$fullyQualifiedMethod_or_class$ as opId | table _time opId All_TPS_Logs.duration</query>
          <earliest>$tps_selection.earliest$</earliest>
          <latest>$tps_selection.latest$</latest>
        </search>
        <option name="height">400</option>
        <option name="timeline_app.timeline.axisTimeFormat">SUBSECONDS</option>
        <option name="timeline_app.timeline.colorMode">categorical</option>
        <option name="timeline_app.timeline.maxColor">#DA5C5C</option>
        <option name="timeline_app.timeline.minColor">#FFE8E8</option>
        <option name="timeline_app.timeline.numOfBins">6</option>
        <option name="timeline_app.timeline.tooltipTimeFormat">SUBSECONDS</option>
        <option name="timeline_app.timeline.useColors">false</option>
        <option name="charting.drilldown">false</option>
      </viz>
    </panel>

Hi

I got an answer to this by changing the `

| tstats summariesonly=$summariesonly_token$

to

| tstats summariesonly=true

This seems to have a great performance effect.
