Browser tools are pretty powerful and can provide a good amount of browser level performance informaiton now. You can probalby pull that data into Excel for graphing. Another alternative is proxy tools like Fiddler that capture HTTP(s) traffic.
Recommend tool for testing/reporting web response time performance
