I'm currently developing a CRM in ASP.NET 4.0. It has a database connection that resides on a separate computer.
The development and dev-hosting of the site is done locally.
Until yesterday everything worked almost flawlessly (except for those part I'm working on), but suddenly all postbacks and redirects slowed almost to a crawl.
And for the life of me I can't figure it out.
I read one blog that said that it's always a good idea to use the overloads for Response.Redirect, and to enter False as the second argument.
So, I changed those in some of the places and I noticed a slight difference in performance. But only when redirecting to a different page.
It's the postbacks that are killing me here.
I make frequent use of UpdatePanels and one of the pages do perform several queries against the database, but that has never been an issue before.
Has anyone any ideas of what the issue can be?
