I have an AJAX / ASP.NET 2.0 website that performs perfectly in a one server IIS 6 environment. However, when that same site is pushed to a two server load balancing environment, the performance drops drastically. Pages take at least 20 - 30 seconds to load in the two server environment. The site uses asp.net UpdatePanel and Scriptmanager. Some XML parsing is done during each page load, but very little. I've ruled out a problem with the actual loadbalancer, server, firewall, etc. I've narrowed it down to it either being a problem with a configuration in the web.config file or a setting in the actual page with view state. Does anyone have any insight? Thanks!

 Hi,

If we create a website that doesn't use AJAX and request it using load balance, does it have the same issue? We need to narrow down the issue.

I look forward to receiving your test results.
