Lazy function parsing, pin parsed scripts in the HTTP cache to reduce latency where possible (the second piece might not be feasible without some major work). Compilation of prefetched scripts might fit in here.
Measure whether JSC-like ropes would help us out (bug 555395) and, if that is hopeful, do it
Improve/import regexp compiler
Create JS microbenchmarking suite and analysis system, and also analyze competing implementation and look for needed improvements
Create "real-world" JS benchmark suite, possibly in collaboration with an intern at MSR

Scope chain rework for JM (see https://wiki.mozilla.org/JaegerMonkey#Major_Optimizations)
Globals reworking for JM (careful--this is high priority)
General JM work: adding compiler fast paths, perf testing
Collaborate with bhackett on type inference-based optimization
