01:12:50  <daurnimator>caitp: I'm tuning a VM written in JS
01:14:59  <daurnimator>caitp: for #1, currently the VM has tagged values: I was curious if I would get an across the board performance gain by using a plain object rather than a class, and the answer seems to be yes
01:34:40  <daurnimator>caitp: re: your concerns about #2, I just created https://jsperf.com/object-freeze-access-performance/1 which seems to have the same conclusion, but not such a large gap.
