We are reported by CA performance Management Center users that recently the dashboard launched on browser could run very slow or browser just like hang there no response. I also notice a few time this week.

The slow down is seen in Chrome browsers. The same slowdown is not seen in Edge browsers.
Out of data Chrome browser caused likely known memory issues locally slowing the completed rendering of Dashboards and Reports.
