+description: Use when profiling paperless-ngx performance, running `manage.py benchmark`, investigating a slow query or endpoint, or deciding whether a profiling finding should become a permanent registered scenario. Covers command reference, the fork/merge-back branch workflow for perf investigations, and how to read query-plan output.
+---
+
+# Paperless-ngx Benchmarking
+
+This repo has a built-in benchmarking/profiling tool: `manage.py benchmark`, in
+the `paperless_benchmark` Django app. It replaces ad hoc standalone scripts —
+use it instead of writing new one-off seed/timing scripts.
+
+## Command reference
+
+```
+manage.py benchmark seed --tier {home,medium,large} [--reset --yes-i-know-this-wipes-the-database] [--seed N]
+manage.py benchmark run --repeat 5 [--label baseline]
+manage.py benchmark profile <scenario_name> [--repeat 5] [--explain]
+manage.py benchmark list-scenarios
+```
+
+- **`seed`** builds a realistic dataset at one of three scales: `home` (500
+  documents — fast, use this for iteration), `medium` (20,000 — the default
+  when `--tier` is omitted; a multi-minute seed), `large` (360,000 — matches
+  the scale reported in real large-install bug reports; slow, only use it
+  when a finding needs confirming at real scale). `--reset` wipes any
+  previously-seeded benchmark data first — but it is destructive and
+  irreversible: it deletes **all** users, **all** groups, and **all**
+  documents/tags/correspondents/document types/storage paths in the target
+  database, not just benchmark-created rows. Only run it against a disposable
+  benchmark database, never a real install. Because of that, `--reset` also
+  requires passing `--yes-i-know-this-wipes-the-database` in the same
+  invocation, or the command raises an error and does nothing. Omit both
+  flags if you want to layer more data onto an existing seed instead. `seed`
+  creates two named users, `perf_target` (mixed owned/shared documents,
+  realistic guardian permission grants) and `perf_admin` (superuser), plus a
+  general user/group pool with realistic permission-row ratios.
+- **`run`** times the 3 built-in API endpoint benchmarks
+  (`/api/documents/`, `/api/documents/?page_size=50`, `/api/tags/?page_size=100000`) for both
+  `perf_target` and `perf_admin`, reporting min/median/max wall-clock and SQL
+  query count. Requires `seed` to have already run — it reuses that data, it
+  does not seed its own.
+- **`profile`** times one named scenario from the registry (see
+  `list-scenarios`) via best-of-N repeat timing and SQL query count, against
+  `perf_target`. `--explain` additionally captures and prints the query plan:
+  real `EXPLAIN ANALYZE` execution stats on PostgreSQL/MariaDB, or
+  `EXPLAIN QUERY PLAN` (plan only, no real timing/row counts — clearly labeled
+  as such) on SQLite. Like `run`, `profile` requires `seed` to have already
+  run — it does not seed its own data either.
+- Every `run`/`profile` invocation appends a JSON line to
+  `benchmark_results/history.jsonl` at the repo root (local-only, gitignored —
+  never commit this file). Use it to compare a `before`/`after` pair across
+  two invocations without hand-copying numbers.
+- Full chain example: `seed --reset` once, then `run` and `profile` as many
+  times as you want against that same seeded data — no need to reseed between
+  them.
+
+## Adding a new scenario
+
+A "scenario" is a named, registered query/operation that `profile` can time
+and explain. To add one, edit `src/paperless_benchmark/scenarios.py`: write a
+`_<name>_run(user)` function (returns whatever `run_profile` should time) and
+optionally a `_<name>_queryset(user)` function (returns the `QuerySet` for
+`--explain` to analyze), then `register(Scenario(name=..., describe=...,
+run=..., queryset_for_explain=...))` at module level. Both functions receive
+the already-seeded `perf_target` user — they should not seed their own data.
+
+## Branch workflow
+
+`tools/benchmark-management-commands` is a **long-lived tooling branch**, not
+a feature branch that gets merged and closed:
+
+1. It is periodically brought up to date with `dev` (merge `dev` into it) so
+   the tooling doesn't drift from the schema/codebase it profiles. Do this
+   before starting a new investigation if it's been a while since the last
+   sync.
+2. **Every performance investigation forks its own branch from
+   `tools/benchmark-management-commands`** (not from `dev`). Do the
+   investigation there: write throwaway profiling code, try fixes, capture
+   before/after numbers.
+3. **That investigation branch never merges into `dev` or production.** Its
+   only job is to produce evidence and, optionally, a reusable scenario.
+4. If the investigation turns up a scenario worth keeping permanently (see
+   "When to graduate a scenario" below), open a PR that adds **just that
+   scenario** back into `tools/benchmark-management-commands` — not the rest
+   of the investigation branch's throwaway code.
+5. Any actual production fix the investigation motivates (e.g. an ORM query
+   change) goes into its own normal feature branch off `dev`, following the
+   project's regular contribution process — profiling evidence informs that
+   PR's description, but the profiling code itself does not travel with it.
+
+## Reading query-plan output
+
+- **PostgreSQL** `EXPLAIN ANALYZE`: look for `Seq Scan` on a large table
+  (missing index), a large gap between `rows=N` (planner's estimate) and the
+  actual row count in parentheses (stale statistics or a bad cardinality
+  estimate), and nested-loop joins driven by an outer relation with many
+  rows (usually the N+1 pattern this tool exists to catch).
+- **MariaDB**: verified against a real MariaDB 12.3 container that MariaDB
+  does NOT accept MySQL 8.0.18+'s `EXPLAIN ANALYZE` syntax (it's a 1064
+  syntax error) -- `capture_explain()` instead runs MariaDB's own
+  `ANALYZE <statement>` form (no `EXPLAIN` keyword), which returns a
+  tabular plan with real per-row execution columns: `rows` (estimate) vs.
+  `r_rows` (actual), and `filtered` vs. `r_filtered`. A large gap between
+  `rows` and `r_rows`, or `type: ALL` (full table scan) on a large table,
+  are the signals to look for -- the same underlying concerns as Postgres's
+  `Seq Scan`/estimate-vs-actual gap, just in MariaDB's column-based output
+  instead of Postgres's nested-tree text format.
+- **SQLite** `EXPLAIN QUERY PLAN`: no real timing/row-count data, only the
+  chosen access path (`SCAN` vs `SEARCH`, which index if any). Useful for
+  confirming an index is even being considered, not for judging real-world
+  cost — corroborate any SQLite finding against Postgres/MariaDB before
+  trusting it, since planner behavior differs meaningfully between them.
+- Compare query **count**, not just timing, between before/after: a fix that
+  keeps the same wall-clock time but drops query count from O(n) to O(1) is
+  still a real, durable improvement — timing alone is noisy and
+  environment-dependent, query count is not.
+
+## Cleaning up after an interrupted run
+
+If a `seed`/`run`/`profile` invocation gets killed mid-run (Ctrl-C, `kill -9`,
+a timed-out SSH session, etc.), check whether it left anything behind before
+trusting the next benchmark's numbers. This was verified for real: a
+`benchmark seed --tier large --reset ...` was started against both a fresh
+PostgreSQL 18 container and a fresh MariaDB 12.3 container and `kill -9`'d a
+few seconds into document seeding. In both cases, the database-side
+connection disappeared immediately -- no stuck backend, no lingering query,
+no held lock was observed in either backend once the killed process's PID
+was confirmed gone. That said, this was one interruption point (mid
+bulk-seed, between chunks); a run killed mid-query, or a driver/network
+hiccup that doesn't cleanly close the socket, could behave differently, so
+still check before trusting a number if any run in the session was
+interrupted:
+
+- **PostgreSQL**: look for leftover connections against the benchmark
+  database:
+
+  ```sql
+  SELECT pid, state, query, query_start
+  FROM pg_stat_activity
+  WHERE datname = current_database() AND pid <> pg_backend_pid();
+  ```
+
+  If a stuck backend shows up, clear it with:
+
+  ```sql
+  SELECT pg_terminate_backend(pid)
+  FROM pg_stat_activity
+  WHERE datname = current_database() AND pid <> pg_backend_pid();
+  ```
+
+- **MariaDB**: look for leftover connections/queries:
+
+  ```sql
+  SHOW FULL PROCESSLIST;
+  ```
+
+  If a stuck connection shows up (anything other than your current admin
+  session), clear it with:
+
+  ```sql
+  KILL <id>;
+  ```
+
+A stray connection left running concurrently with a subsequent benchmark run
+would add real, contaminating load (extra queries competing for the same
+rows, possibly held locks slowing the next run's timings) -- cheap to rule
+out, expensive to silently trust a number that was actually measured
+alongside a zombie connection.
+
+## When to graduate a one-off finding into a permanent scenario
+
+Register a scenario (rather than leaving it as throwaway code on the
+investigation branch) when **both** are true:
+
+- The query pattern is one this codebase is likely to regress on again (e.g.
+  it involves a permission-check join, a bulk operation, or anything else
+  with an easy-to-reintroduce N+1) — not a one-time fluke specific to this
+  investigation.
+- Re-running it later, against a fresh seed, would still produce a
+  meaningful signal (it doesn't depend on investigation-specific throwaway
+  data or a fix that's already permanently landed and can't regress the same
+  way).
+
+If a finding doesn't meet both bars, keep it as disposable code on the
+investigation branch and let the branch's evidence (captured in the PR
+description of whatever production fix it motivates) be the permanent
+record instead.

-    Bulk equivalent of set_permissions_for_object: applies the same

-
-    Takes a model + pks (rather than model instances) deliberately -- the
-    permission rows built below only ever need `pk`, `content_type`, and
-    identity ids, so callers shouldn't have to fetch full rows (with every
-    other field) just to hand them to this function.

-    passing a list as the object routes to bulk_assign_perm, which skips
