Benchmarks: https://github.com/facebookincubator/cinder/blob/cinder/3.8/...

There are some perf hits, as well as all the improvements.

It’s worth noting that we’ve never targeted perf on any of these benchmarks, so these are just the results that fell out from optimizing for our production workload, which is a totally different beast.

Most of the hits are due to the default “JIT everything” behavior which is really bad if there are a lot of rarely called functions, but would be easy to fix. This is discussed in the README.

How does this compare to other interpreters?
