>
> Ambari UI when logging-in requests the persisted cluster status from the 
> /api/v1/persist/CLUSTER_CURRENT_STATUS call. On a 800 node cluster this takes 
> 2s or more to GET.
> The majority of time is in the transfer of bytes. 
> A 3.8s call had a wait time (time to first byte) of 815ms, and content 
> download time of 2.98s.
> We need to see if the download time can be improved.
