Jun 1, 2026June 2026 monthly summary for ModelTC/lightllm. Implemented a runtime profiling system to enhance observability and performance tuning. The system integrates PyTorch Profiler and NVTX, exposes HTTP endpoints to start and stop profiling sessions dynamically during server operation, and uses an RPyC-based communication service to propagate profiling commands across distributed router processes. This work was shipped under the commit 41ed8e91149d0f4ca4e7655ddbb9f96d889a6874 with the message 'basic Profiler support (#1247)'.
