The fastest streaming example on that list (csv-parser) is still 5× slower than Python.
Which I'd assume has to do with the overhead of dispatching a ton of asynchronous events for relatively little parsed data rather than the intrinsic speed of node, the fastest synchronous parsers of the list are about on-par with Python.

But Java conceptually has a lot of drawbacks that require the JVM to have screaming performance to compensate for. Almost everything being a "headered" object being probably the worst offender. Even a slightly worse Go compiler is probably well compensated-for by denser data structure layout in the operating memory.
> Java conceptually has a lot of drawbacks In what sense is an articulated object a "conceptual drawback"? It is a richer object model and SMI and friends had the engineering chops to makes it highly performant.
