One way to make it run faster is by enabling the Client Cache mode from Sitefinity's settings.
You go to Administration->Settings->Advanced->System->Output cache settings then you check the 'Enable Client Cache' check box.
If the "Default Output Cache Profile" on the same section is set to "Standard Caching" then you can go two levels deeper in the settings tree to "Client Cache Profile-> Standard Caching" and set the the expiring time duration in seconds in "Duration" field.
Hope this helps.
