Here’s a great tip that worked for me to help speed up how quickly Dreamweaver CS6 opens files for the first time:

“When you try to open a document in Dreamweaver CS6, it takes anywhere from 30 seconds to several minutes for Dreamweaver to open it. Dreamweaver stops responding until the document opens.

Solution:
Disable Dreamweaver’s Resolve To IP Address feature using the instructions for your operating system.

1. Quit Dreamweaver.
2. In the Finder, navigate to the following location: /Users/Your User Name/Library/Preferences
3. Open the Adobe Dreamweaver Prefs file in TextEdit.
4. Locate the [REMOTE DOWNLOAD] section in the file.
5. At the bottom of this section, add a line that says: resolveremoteurltoipaddress=FALSE
6. Save file.
