jdx bench

$ jdx bench --help
Usage: jdx bench [<options>]

  Benchmark the read path: run the fixed load/show/members/search/hierarchy workload against the resolved roots and print the timing table with PROPOSAL.md §15 targets. Roots resolve like the read commands (--jars plus the selected workspace plus the JDK unless --no-jdk); with no explicit roots and no workspace selected, the local minecraft-client.jar is used when present. Targets are advisory: success always exits 0. Example: jdx bench --iterations 1.

Options:
  --jars=<text>           Binary roots: jar files, class directories or globs (repeatable). Merge in front of the selected workspace's roots.
  --src=<text>            Source-dir roots (repeatable). Merge in front of the selected workspace's stored srcs.
  -w, --workspace=<text>  Use a named workspace (see jdx ws). Explicit --jars merge in front of it.
  --no-jdk                Do not include the running JDK's stdlib (included by default).
  --coord=<text>          Maven coordinate root group:artifact:version (repeatable).
  --repo=<text>           Maven repository base URL for --coord fetches (repeatable).
  --fetch                 Allow downloading --coord artifacts from Maven repositories.
  --iterations=<int>      Runs per case; the median is reported (default 3).
  --json                  Emit machine-readable JSON instead of human-readable text (same information, D-007).
  -h, --help              Show this message and exit
