Java’s collectors vastly outperform Go’s. Look at the Debian binary tree benchmarks [0]. Go just uses less memory because it’s AOT compiled from the start and Java’s strategy up until recently is to never return memory to the OS. Java programs are typically on servers where it’s the only application running.

IIRC the native image GC is still the serial GC by default. Which would probably perform the worst out of all the available GCs.

I know on HotSpot they’re planning to make G1 the default for every situation. Even where it would previously choose the serial GC.
