Pre-requisite:
    Create a directory e.g. C:\test and place the following index.html file in it.

    index.html
    ==========
    <h1>Hello World</h1> 

    From within this C:\test directory run `python -m SimpleHTTPServer 80`

What steps will reproduce the problem?
(1) Build content_shell and chrome targets on Windows
(2) Launch content_shell as
out\content_shell http://localhost --trace-startup --trace-startup-duration=10 --trace-startup-file=content_shell_trace.json

(3) Launch chrome as
out\chrome http://localhost --trace-startup --trace-startup-duration=10 --trace-startup-file=chrome_trace.json

What is the expected output?
The loading time should be same either on chrome or content_shell

What do you see instead?
Load time on content_shell is significantly high
