Compilation is very slow
I moved from version 1.14 to version 2.0.
Same symptoms (build very, very slow), and also in my case disabling _all_ network connections restores normal compilation speed.
This is a serious issue, I usually use 2 or 3 network devices at the same time for different purposes.
The system is windows 7 professional, 64 bit.

Adriano
