Rust accelerators boost LangGraph agent performance up to 10x

A new set of Rust accelerators, named fast-langgraph, has been developed to significantly speed up critical operations within the LangGraph framework. These accelerators, designed as drop-in replacements, target bottlenecks such as state serialization, state management, and redundant LLM calls. While automatic acceleration offers a 2-3x speedup with no code changes, direct component replacement, like using the RustSQLiteCheckpointer, can yield up to 6x faster checkpointing, and an LLM cache can provide a 10x improvement with a high hit rate.
