Console slow - how to find out cause ?

Anyway I can find out what makes the console so slow. Its something we have just lived with but decided to do something about it now.

Any helpful pointers!

Example : Click on manage computers - it takes 20 seconds to complete showing all the computers (we have 1100 machines in the console 800 managed)

From there i click on manage - -> jobs / tassks. It takes 14 seconds to complete.

From there manage policies and it takes 8 seconds.

be curious to see what other users reposnse speeds are.

Thanks
