Question

 

1) Default setting 

slowest speed as about 22 seconds waiting time for each map move

2) Reduce rendering limit

will speed up 30%. Increase this limit will slow down but you get more feature each pull

3) simplify the polygon by reduce the total point count of each polygon

will further speed up to 1 second waiting time
