# script/bench: run the Go benchmarks of internal/handlers, which serve
# cache hits in parallel through the image handler and report the hits
# served per second. A benchmark, not a check: script/check does not run
# it. It builds the bench phase of the Dockerfile alone, as script/test
# builds the test phase, with plain progress output so that the
# benchmark's results are shown. A new CACHEBUST value reruns the
# benchmark on every build. --output type=cacheonly writes no image.
