===== Performance ===== 
In the Diagnostics -> Performance page you can inspect a statistical measure of the performance of PMA.core. 
The page displays the average time it takes for PMA.core to serve a request. The page is split in two parts one for //hourly averages// and one for //daily averages//. 

  * Number of requests: The number of requests served by PMA.core
  * Mean: The average time to complete a request
  * Deviation: The standard deviation of the time taken by the requests

Those statistical measures are calculated for today, yesterday, two days ago, three days ago, four days ago, a week ago and a month ago. 

That way you can inspect the performance of PMA.core over time and visually detect any significant statistical differences in the average or the standard deviation.
