Manage over 10000 annotations on MapKit view

do you have some strategy for manage over 10000 annotations on a small area inside a MapKit view... I have set a filter for manage that when the开发者_运维技巧 user change the zoom level but with over 10000 iterations it's very slow....

Thanks

What is usually done is merge several annotations that are close to each other into only one and show them in more detail once the user zooms in. Would that work for you?
