Answer 1

In addition to the felickz's answer which solves (or almost solves) this problem for builds:

Except the problem during a build I also had problem with the Package Management Console. It took about a minute to wait for it. Using the procmon I found that the NuGet repository folder was parsed each time this window is opened (very smart, Microsoft!). There were about 1000 packages in this folder. After removing everything from the above folder the performance problem diapered.
