We would like to implement the function of Addfeature in openlayers to draw lines and push them onto a vector layer, and overlay this layer onto open street map or google map. Those lines are draw dynamically based on the query results from the database.
The only concern so far is the performance issue since we are anticipating about 3000 lines per operation. Has anyone worked on this kind of project before? Do you think it is too heavy on the client side?
