Can ClusterStrategy be useful in this case??

Zac,

thanks for your response. I know IE sux, but 95% of our customers have IE6 installed, and they are not allowed to switch to another version or to get other browsers.

I get the polygons from GeoServer from a wfs layer. They are complex polygons with lots of vertices (parcels from cadastre) and I can't simplify the features because we are on the task of online editing using wfs-t protocol, so the edition must be accurate.

I'm just wondering if there is something that I can show, like a progress bar or loading image, to tell the user this kind of operations will take a bit, but I'm afraid is going to be difficult because of the browser program.

Any idea?

Regards,

Un saludo,

short answer, IE just sucks

long answer, you could switch over to a real mapserver engine

how dense are your polygons? generalising them might help a bit if they are very dense

	Hi list,

	I'm having some performance issues with most browsers, but specially with IE (this is the real problem).I have a vector layer in which once the map is shown I load from 50 to 100 polygons and I zoom to them. I know that this is a task it will consume some time, but the problem is that the browser gets freezed and I would like to improve that in order to improve the user experience.

	I've tried this in

	FF --> 5-10 seconds
	Safari --> 5 seconds
	Chrome --> 5 seconds
	Opera --> 5 seconds
	IE6 --> 60 seconds
	IE7 --> 40 seconds
	IE8 --> 30 seconds

	Is there something that I can do to improve the browser's response??

	Thanks.
