Has the map changed during the 40ms, like panning or zooming?
Is there objects on the map which has changed?

Don't repaint all layers, only those who might have changed.

Repaint only on changes of data.

If there is a burst of events, coalesce during a timeperiod and then
repaint using javax.swing.Timer .

These are the measures that I have made in my Openmap app.
