Collecting cache miss rate of browsing websites using Chrome

[hanyun_t_]

Hello, 

I'm new to Vtune and want to use it to learn the overall cache miss rate of browsing websites using Chrome for a long time period (around 30 mins). I've read the notes about how  to record cache miss event with Vtune. The problem I have so far is, after I start the analysis, chrome is launched and the analysis stopped immediately after the first website is loaded. How could I keep the analysis on for a period of time so I can collect the data of browsing different website?

Hello,

One possible way to resolve this is to profile in system-wide mode. To do this go to project settings and change the combo-box on the top from 'Launch Application' to 'Profile System'. 

Also note that by default VTune limits collected data by 500MB - since you are going to profile for a long period you'll probably need to increase it (setting it to 0 will disable the limitation at all).
