I think 30 vector layers is farm too much for dealing with in a Browser. You should switch to WMS layers unless you need to edit or create new vectors.
Regards, Robert Sanson >>> João Rodrigues<joaorod...@gmail.com> 4/11/2014 10:13 a.m. >>> Hi I have a GIS SDK with WMS layers and Vector layers (with information from Geoserver). I have methods for setting a style map, but I have a performance problem. When I set same style for 30 layers, for example, the UI gets very slow because the 30 layers have to refresh. Is it possible to reduce the refresh time for the layers? I have been thinking about some this, but I need some advice: a) Is it possible to refresh vector layers **without** downloading the whole WFS data again? I just want to set a style with some rules. b) Is it possible to reduce the refreshing time of WMS layers, maybe juggling with the number/size of the tiles (I am using single tile now)? c) I tried creating a layer group in Geoserver <http://docs.geoserver.org/latest/en/user/webadmin/data/layergroups.html>, but I don't know how I can apply a style to each of its layers. I don't even know if it is possible to manipulate the layers individually when they are in a layer group. Is it possible? I would appreciate some advice. Thank you PS: When I change zooms or when I pan the map, it is very slow too. I think it is related to this question, so I leave it as a P.S.
