Graphics on IE Hopelessly slow

FrankConry — Fri, 18 Feb 2011 00:09:56 GMT

I'm having a problem displaying a map with graphics in Microsoft Internet Explorer. I need to display about 10k graphics (the specific graphic doesnt matter) and my application kills Internet Explorer. Even the ESRI samples go super slow and give the following error in IE8:

Stop Running this Script?

A script on this page is causeing internet explorer to run slowly. If it continues to run your computer may become unresponsive.

I have tried the folloing samples:

I have some modified examples with displayGraphicsOnPan false:

I am almost finished with my application and this IE error inexplicably showed up, any help would be much appreciated.

10k graphics is about 10 times as many as you should ever put on a web map, IMO. Even in browsers with high performance JS/rendering capabilities, I wouldn't expect a map with 10k graphics dropped on it to perform well. I think you should look into either clustering your data or using a dynamic map service.

Can you give me a link as far as a Dynamic Web Service?

The app is super fast in chrome and FF, so I didnt really think that it would be a problem.

For general info on dynamic map services, start here: http://help.arcgis.com/en/arcgisserver/10.0/help/arcgis_server_dotnet_help/index.html#/What_is_a_map_service/00930000004q000000/

Here's the doc that explains usage with the JS API: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/arcgisdynamicmapservicelayer.htm

Yeah a static map made and uploaded won't work at all. Any other thoughts? Anyone?

A dynamic map service != "static map made and uploaded".

How about clustering? You still send all your data to the client but display far fewer graphics.
