Mmm, agree with parent; can get faster. Unfortunately lots of perf critical code is created out of necessity and defaults to proprietary.

You could profile this lib and figure out where it’s spending most of its time and figure out if there any ways to improve (starts getting into implications of JS <-> system), but as you get more idiosyncratic you lose flexibility and ease of use.

Eg type checks, heap additions, recursion, etc can get “slow”
