Researchers have developed PerfAgent, a novel system designed to enhance the code optimization capabilities of large language model (LLM) agents. Unlike previous agents that focused on correctness, PerfAgent uses profiler-guided iterative refinement to identify and address performance bottlenecks. This approach allows agents to achieve speedups comparable to human experts, even when dealing with complex codebases that include abstraction layers and native extensions. In evaluations on the GSO and SWE-fficiency-Lite benchmarks, PerfAgent significantly improved the rate of expert-matching patches, more than doubling it compared to existing methods. AI
