Visual Studio 2012 now very slow when starting to debug a website
Posted on 2013-01-03
I'm working on a .NET 4 website which accesses a sql server database, using Visual Studio 2012 Pro (version 11.0.51106.1 Q11REL)
When I hit "Start Debugging", it launches IE9 (blank), then loads symbols, then displays the specific page in the start action.
Suddenly last week, I went from seeing my page in about 5 seconds to 30-60 seconds!
I didn't change anything significant on my machine (I don't think; maybe I installed Update 1 to VS 2012?).
Update: it's not Update 1. I uninstalled and reinstalled from DVD, and it's still super slow. I even defragged the hard drive before reinstalling.
More specifically, I see the "loading symbols for..." messages, in VS' status bar, at a rate of about 1-2 per second, which is absurd.
- this is on a fast laptop (i5, lots of memory, lots of free hard disk space, low CPU utilization)
- the project is set to use VS Development Server and only debug ASP.NET (Edit and Continue is disabled)
- it doesn't matter if I access my local copy or a remote copy of the database
