Im using System Explorer 6.0.1 to monitor CPU usage on my Windows computer.
When i click to open new Tab in Google Chrome, i see it is lagging during opening/loading new tab elements and CPU usage is 100%, this spike takes around 2 seconds. and it is 3 seconds to load new tab.

When i deactivate all Cheome extensions, speed increase / 100% load time decrease is negligible. I did not tried to restart Chrome.
