Application running very slow on public side

JustinNettleton — Mon, 29 Oct 2012 14:24:52 GMT

I have created a Flexviewer application and I am having problems with it rendering very slowly on the public viewing side. Depending on the computer and Internet Speed, it takes up to 30-60 seconds for the page to fully load. Our ArcGIS server is not public so I set up a virtual directory on our Counties webserver connecting to the application on our ArcGIS server. I am using a proxy page to get to the data out.

Does any else have this problem? Could the proxy be what is slowing this down? I have most of the data in the mapped cached so I don't think that is the problem.

Have you tried using a tool like HttpFox or Charles Proxy to see how long each request is taking? This may help narrow down where the problem is. Also, can you share the URL to your Viewer?

I will give those tools a try to see if I can find anything out. I changed a couple settings on the services and it seemed to help a little bit. Here is the link anyway.

I don't use a proxy server, so can't "play" with that.

I know I have had some timing issues in the past as my server was attempting to resolve the IP addresses. Might be worth a shot to put the fully qualified domain name (or IP address) in for your services instead of just Vulcan"

also, don't think it's related to speed, but the TOC widget documentation clearly states that you should set the mapswitcher <layerlist visible="false"> if running the TOC to avoid layer ordering issues and such.

I have made the IP change you suggested and it seems to have helped a little bit.

I have also made the mapswitcher change. I looked over the bit in the documentation.

Thanks,
