Steps to reproduce the problem:
1. run chrome with --user-data-dir option pointing to a new directory, on machine with internet access, to an intranet site. Measure the time from clicking the exe to when the URL bar becomes responsive
2. Repeat the above steps after turning the internet on
3. Compare the times, they will be different (in our case 10 sec difference!.

What is the expected behavior?
chrome started with --user-data-dir should start up with the same speed regardless of the computer having the internet connection or not

What went wrong?
Chrome becomes responsive in much longer time, when the machine does not have internet access and is started with --user-data-dir parameter.

Did this work before? N/A
