When using the experimental esbuild-based browser application builder, initial debug performance profiling information can now be output to the console by using the `NG_BUILD_DEBUG_PERF` environment variable. When enabled, duration information for elements of the Angular build pipeline will be shown on the console. Certain elements marked with an asterisk postfix represent the total parallel execution time and will not correlate directly to the total build time. This information is useful for both experimentation with build process improvements as well as diagnosing slow builds.
