Root cause: render-worker and render-worker-light shared the same GPU, causing contention. Complex TRB renders went from 17s → 36s (2x slower). Changes: - Thumbnails back to asset_pipeline queue (not asset_pipeline_light) - Dispatch routing always uses asset_pipeline (no queue splitting) - render-worker-light gated behind "multi-gpu" profile — only starts with: docker compose --profile multi-gpu up -d - For single-GPU setups: all rendering is sequential on one worker The dual queue approach is correct for multi-GPU machines where each worker gets its own GPU. On single-GPU, serial execution is faster than concurrent GPU contention. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
