This benchmark should provide a relatively realistic scenario for reference scanning. As shown by the following results, reference scanning code is already plenty fast and is definitely not a bottleneck: ``` BM_RefScanSinkRandom/10000 1672 ns 1682 ns 413354 bytes_per_second=5.53691Gi/s BM_RefScanSinkRandom/100000 11217 ns 11124 ns 64341 bytes_per_second=8.37231Gi/s BM_RefScanSinkRandom/1000000 205745 ns 204421 ns 3360 bytes_per_second=4.55591Gi/s BM_RefScanSinkRandom/5000000 1208407 ns 1201046 ns 597 bytes_per_second=3.87713Gi/s BM_RefScanSinkRandom/10000000 2534397 ns 2523344 ns 273 bytes_per_second=3.69083Gi/s ``` (Measurements on Ryzen 5900X via `nix build --file ci/gha/tests componentTests.nix-store-tests-run -L`)
