The xpconnect overhead should have disappeared with the new c++ csp
implementation that Sid's team landed. The hardcoded implementation of
the certified apps csp is still there though, and will be hard to beat
perf wise. I'm not sure how many resources the app is loading at
startup, but the csp cost is mostly linear with the resource number and
that adds up.
