Unfortunately for FIrefox it also doesn't fare well on JavaScript-heavy real world cases. 280slides is noticeably faster on Mulproc and Opera in my experience destroys the competition on Google Maps (though this is probably in part due to their rendering library Vega). Or what about the SNES emulator written in JavaScript? It may not be your typical web application but it painfully shows the limitations of Firefox' current engine. TraceMonkey missed the market requirements in parts. The whole two JavaScript engines approach is also not without its wart like having two different assemblers now.
