[OpenLayers-Users] LoadingPanel - Waiting for Vector & WFS loading

[Phil Scadden]

I use the LoadingPanel control (it may be an extension). Maximize just 
before the read operation and minimize at end of wfs handler function.

That said, using WFS for vector layers isnt great. I would strongly 
consider the strategy of WMS for display and WFS for query. Because the 
query returns a subset (and you can specify only the attributes you want 
in propertyNames), it is much faster.  You can use SLDSelect when you 
have huge geometries that could be selected. WMSGetFeatureInfo control 
with hover true can you much of the functionality of vector layers 
without bringing down and trying to draw it on the client.
