问题
Since upgrading visual studio 2015 and using ssis, we have experienced that the editor for Script Task/Component takes around 30 seconds to open.
i have seen some older posts suggesting to add "127.0.0.1 crl.microsoft.com" to the local hosts file. But has not impact on the issue i'm experiencing.
Really hope someone out there has had the same issue and maybe found a solution?

Try to clean up your temp folder, could help if you use it for temp files in your etl
C:\Users\UserName\AppData\Local\Temp
One more thing - did you get an new antivirus lately or changed policies ? Once I had this problem and Sophos really killed any performance of my visual studio. We set it to reads only and performance went up.
