The main performance increase from pulling tiles from multiple hosts is actually due to working around the RFC-recommended limitation of two HTTP connections per host. I believe that you can work around this in the MapGuide OpenLayers data source by setting your data source to be a list of servers rather than a single server (which could all be CNAMEs pointing to the same host). There is a ticket for exposing this capability in Fusion, but I don't believe that it has been addressed:
http://trac.osgeo.org/fusion/ticket/137 There are quite a few other ways that MapGuide tiling performance could be improved. Zac covers this in his blog: http://tinyurl.com/cmtyxc Serving files via HTTP is actually pretty darn cool, because you could use it to serve MapGuide tiles from something like Amazon's CloudFront. If you had MapGuide running under EC2, this would be a natural.

This would be a great performance advance. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
