low-overhead

Ken Jin's blog describes Python 3.15's new ultra-low overhead interpreter profiling mode that uses dual dispatch tables to enable efficient trace recording for the JIT compiler, reducing slowdown compared to previous approaches.

Akashic introduces MemAttention, a low-overhead memory system for LLM inference that organizes context into bounded chunks and models semantic relationships, improving accuracy by up to 10.2 points and throughput by up to 1.21× over prior baselines.
