SSMS Extremely Slow connecting to local dev db So I found this question and believe this is related.
SQL Server Management studio slow connection or timeout when using Windows Authentication

If I extend my timeout to 30 seconds I get SSMS connected but everything is terribly slow!  The application is extremely slow/timing out when debugging.

They mention adding an entry to the hosts file to bypass DNS lookup.  This is a local dev db running on my machine.  What would I add to the hosts file to eliminate these DNS issues???  Servername = "ROG-DREAM-MACHI\SQLDEV".

I'm a db noob.  Plz help. :(
Your DNS entry in the C:\Windows\System32\drivers\etc\hosts file will be:

ROG-DREAM-MACHI   127.0.0.1


You'll need to use Notepad with administrative rights, to be able to make any changes to that file.

(However, I'm voting to close this question as a duplicate of the one you posted.)
