The Comfy Desktop team shipped an early-stage upgrade that lets you run performance tests on local ComfyUI instances and compare results across sessions. Workflow: start an instance from Comfy Desktop, build a working workflow and export it in API format, then use the hamburger menu > Performance Tests to pick your instance, upload the workflow, set measurements, and run. Multiple test sessions can be visualized and compared side by side in the Benchmarks page. Feedback is being collected to gauge community interest.
