For understanding the web performance, while we have great tools like
Firebug, Page Speed, YSlow!, and Chrome/Safari Developer Tools on the
desktop, unfortunately no such tools exist for mobile browsers. To
start, we built a tool that allows us to analyze mobile browser
network characteristics, which we’re releasing today. Using open file
formats PCAP and HAR, and open source tools pcap2har, HAR Viewer, and
Page Speed, we put together the PCAP Web Performance Analyzer at
http://pcapperf.appspot.com/.
