Benchmarking shows that optimizing Java code (e.g., reducing SLF4J logging) has a far greater impact on latency than choosing a garbage collector, especially at high percentiles.
pon is a new JIT and ahead-of-time compiler for Python 3.14, written in Rust, that compiles Python directly to machine code without an interpreter or bytecode, using a garbage collector instead of reference counting.
