Is anyone else experiencing slow load times on the initial welcome page rendering?
We are seeing a 7 to 8 second delay where we see a blank white page while waiting for the welcome page to render. The response from IBM Support was less than satisfying as we were told they see the same thing in their test environments and it is the IIS URL rewrite causing the delay.
I've tried using Fiddler to narrow down the delay and have had limited luck.
One other thing we noticed is even if the SSO URL Rewrites are disabled, the login page does not render through IIS as quickly as going directly against the dispatcher.
If you press F12 in your web browser you can use the profiler to see which part is taking the most time. This is similar to Fiddler but more web based. Unfortunately even then you can get a inconclusive answer
We've experienced the same thing on our environment, and definitely due to the rewrite rules. Dispatcher login is very fast. I think IIS is just not processing the various rewrite rules fast enough.
