Web console version of Control Center, when selecting statistics for a server, returns (attempts) all of the statistics for the server selected by default during the initial selection.
Our environment holds 90 days of data, and the delay in returning the initial screen of information for some servers is significant. When using the same option for the GUI, you are presented with a list of options to limit how much data is pulled back and where to start the search from.
The web interface should perform in a similar manner or reduce the number of days that are returned by default in the initial request. At a minimal, it should return the data with the most current statistics first.
