In explorer, we already support parsing a string_view, so use that. In toolchain, we need to build support, probably using vfs, so that's a todo. bazel test //explorer:file_test --runs_per_test=5 - branch: Stats over 250 runs: max = 18.3s, min = 5.2s, avg = 11.2s, dev = 2.9s - trunk: Stats over 250 runs: max = 22.3s, min = 5.9s, avg = 12.1s, dev = 2.8s Not a dramatic improvement, but maybe more effective long-term, and this'd been requested on #2876
