Profiling IPC Messages in Fennec

Bug 596725 has a Python script that can profile the IPC messages log. Here's the output when run on icanhascheezburger: link. Some first impressions:
  • A few sync/rpc methods are used quite frequently, like preferences, cookies, permissions. Thankfully these complete very quickly. Still this might be worth optimizing though?
  • Lots of http is going on, so lots of http messages. Maybe nothing we can do about that?
