+# Benchmarks
+
+Currently this repository hosts two kinds of benchmarks:
+
+1. The older "milli benchmarks", that use [criterion](https://github.com/bheisler/criterion.rs) and live in the "benchmarks" directory.
+2. The newer "bench" that are workload-based and so split between the [`workloads`](./workloads/) directory and the [`xtask::bench`](./xtask/src/bench/) module.
+
+This document describes the newer "bench" benchmarks. For more details on the "milli benchmarks", see [benchmarks/README.md](./benchmarks/README.md).
+
+## Design philosophy for the benchmarks
+
+The newer "bench" benchmarks are **integration** benchmarks, in the sense that they spawn an actual Meilisearch server and measure its performance end-to-end, including HTTP request overhead.
+
+Since this is prone to fluctuating, the benchmarks regain a bit of precision by measuring the runtime of the individual spans using the [logging machinery](./CONTRIBUTING.md#logging) of Meilisearch.
+
+A span roughly translates to a function call. The benchmark runner collects all the spans by name using the [logs route](https://github.com/orgs/meilisearch/discussions/721) and sums their runtime. The processed results are then sent to the [benchmark dashboard](https://bench.meilisearch.dev), which is in charge of storing and presenting the data.
+
+## Running the benchmarks
+
+Benchmarks can run locally or in CI.
+
+### Locally
+
+#### With a local benchmark dashboard
+
+The benchmarks dashboard lives in its [own repository](https://github.com/meilisearch/benchboard). We provide binaries for Ubuntu/Debian, but you can build from source for other platforms (MacOS should work as it was developed under that platform).
+
+Run the `benchboard` binary to create a fresh database of results. By default it will serve the results and the API to gather results on `http://localhost:9001`.
+
+From the Meilisearch repository, you can then run benchmarks with:
+
+```sh
+cargo xtask bench -- workloads/my_workload_1.json ..
+```
+
+This command will build and run Meilisearch locally on port 7700, so make sure that this port is available.
+To run benchmarks on a different commit, just use the usual git command to get back to the desired commit.
+
+#### Without a local benchmark dashboard
+
+To work with the raw results, you can also skip using a local benchmark dashboard.
+
+Run:
+
+```sh
+cargo xtask bench --no-dashboard -- workloads/my_workload_1.json workloads/my_workload_2.json ..
+```
+
+For processing the results, look at [Looking at benchmark results/Without dashboard](#without-dashboard).
+
+### In CI
+
+We have dedicated runners to run workloads on CI. Currently, there are three ways of running the CI:
+
+1. Automatically, on every push to `main`.
+2. Manually, by clicking the [`Run workflow`](https://github.com/meilisearch/meilisearch/actions/workflows/bench-manual.yml) button and specifying the target reference (tag, commit or branch) as well as one or multiple workloads to run. The workloads must exist in the Meilisearch repository (conventionally, in the [`workloads`](./workloads/) directory) on the target reference. Globbing (e.g., `workloads/*.json`) works.
+3. Manually on a PR, by posting a comment containing a `/bench` command, followed by one or multiple workloads to run. Globbing works. The workloads must exist in the Meilisearch repository in the branch of the PR.
+  ```
+  /bench workloads/movies*.json /hackernews_1M.json
+  ```
+
+## Looking at benchmark results
+
+### On the dashboard
+
+Results are available on the global dashboard used by CI at <https://bench.meilisearch.dev> or on your [local dashboard](#with-a-local-benchmark-dashboard).
+
+The dashboard homepage presents three sections:
+
+1. The latest invocations (a call to `cargo xtask bench`, either local or by CI) with their reason (generally set to some helpful link in CI) and their status.
+2. The latest workloads ran on `main`.
+3. The latest workloads ran on other references.
+
+By default, the workload shows the total runtime delta with the latest applicable commit on `main`. The latest applicable commit is the latest commit for workload invocations that do not originate on `main`, and the latest previous commit for workload invocations that originate on `main`.
+
+You can explicitly request a detailed comparison by span with the `main` branch, the branch or origin, or any previous commit, by clicking the links at the bottom of the workload invocation.
+
+In the detailed comparison view, the spans are sorted by improvements, regressions, stable (no statistically significant change) and unstable (the span runtime is comparable to its standard deviation).
+
+You can click on the name of any span to get a box plot comparing the target commit with multiple commits of the selected branch.
+
+### Without dashboard
+
+After the workloads are done running, the reports will live in the Meilisearch repository, in the `bench/reports` directory (by default).
+
+You can then convert these reports into other formats.
+
+- To [Firefox profiler](https://profiler.firefox.com) format. Run:
+  ```sh
+  cd bench/reports
+  cargo run --release --bin trace-to-firefox -- my_workload_1-0-trace.json
+  ```
+  You can then upload the resulting `firefox-my_workload_1-0-trace.json` file to the online profiler.
+
+
+## Designing benchmark workloads
+
+Benchmark workloads conventionally live in the `workloads` directory of the Meilisearch repository.
+
+They are JSON files with the following structure (comments are not actually supported, to make your own, remove them or copy some existing workload file):
+
+```jsonc
+{
+  // Name of the workload. Must be unique to the workload, as it will be used to group results on the dashboard.
+  "name": "hackernews.ndjson_1M,no-threads",
+  // Number of consecutive runs of the commands that should be performed.
+  // Each run uses a fresh instance of Meilisearch and a fresh database.
+  // Each run produces its own report file.
+  "run_count": 3,
+  // List of arguments to add to the Meilisearch command line.
+  "extra_cli_args": ["--max-indexing-threads=1"],
+  // List of named assets that can be used in the commands.
+  "assets": {
+    // name of the asset.
+    // Must be unique at the workload level.
+    // For better results, the same asset (same sha256) should have the same name accross workloads.
+    // Having multiple assets with the same name and distinct hashes is supported accross workloads,
+    // but will lead to superfluous downloads.
+    //
+    // Assets are stored in the `bench/assets/` directory by default.

+      // If the assets exists in the local filesystem (Meilisearch repository or for your local workloads)
+      // Its file path can be specified here.

+      "local_location": null,
+      // URL of the remote location where the asset can be downloaded.
+      // Use the `--assets-key` of the runner to pass an API key in the `Authorization: Bearer` header of the download requests.
+      // `null` if the asset should be imported from a local location.

+### Adding new assets
+
+Assets reside in our DigitalOcean S3 space. Assuming you have team access to the DigitalOcean S3 space:
+
+1. go to <https://cloud.digitalocean.com/spaces/milli-benchmarks?i=d1c552&path=bench%2Fdatasets%2F>
+2. upload your dataset:
+   1. if your dataset is a single file, upload that single file using the "upload" button,
+   2. otherwise, create a folder using the "create folder" button, then inside that folder upload your individual files.
+
+## Upgrading `https://bench.meilisearch.dev`
+
+The URL of the server is in our password manager (look for "benchboard").
+
+1. Make the needed modifications on the [benchboard repository](https://github.com/meilisearch/benchboard) and merge them to main.
+2. Publish a new release to produce the Ubuntu/Debian binary.
+3. Download the binary locally, send it to the server:
+  ```
+  scp -6 ~/Downloads/benchboard root@\[<ipv6-address>\]:/bench/new-benchboard
+  ```
+  Note that the ipv6 must be between escaped square brackets for SCP.
+4. SSH to the server:
+  ```
+  ssh root@<ipv6-address>
+  ```
+  Note the ipv6 must **NOT** be between escaped square brackets for SSH 🥲
+5. On the server, set the correct permissions for the new binary:
+   ```
+   chown bench:bench /bench/new-benchboard
+   chmod 700 /bench/new-benchboard
+   ```
+6. On the server, move the new binary to the location of the running binary (if unsure, start by making a backup of the running binary):
+  ```
+  mv /bench/{new-,}benchboard
+  ```
+7. Restart the benchboard service.
+  ```
+  systemctl restart benchboard
+  ```
+8. Check that the service runs correctly.
+  ```
+  systemctl status benchboard
+  ```
+9. Check the availability of the service by going to <https://bench.meilisearch.dev> on your browser.

+### Logging
+
+Meilisearch uses [`tracing`](https://lib.rs/crates/tracing) for logging purposes. Tracing logs are structured and can be displayed as JSON to the end user, so prefer passing arguments as fields rather than interpolating them in the message.
+
+Refer to the [documentation](https://docs.rs/tracing/0.1.40/tracing/index.html#using-the-macros) for the syntax of the spans and events.
+
+Logging spans are used for 3 distinct purposes:
+
+1. Regular logging
+2. Profiling
+3. Benchmarking
+
+As a result, the spans should follow some rules:
+
+- They should not be put on functions that are called too often. That is because opening and closing a span causes some overhead. For regular logging, avoid putting spans on functions that are taking less than a few hundred nanoseconds. For profiling or benchmarking, avoid putting spans on functions that are taking less than a few microseconds.
+- For profiling and benchmarking, use the `TRACE` level.
+- For profiling and benchmarking, use the following `target` prefixes:
+  - `indexing::` for spans meant when profiling the indexing operations.
+  - `search::` for spans meant when profiling the search operations.
+
+### Benchmarking
+
+See [BENCHMARKS.md](./BENCHMARKS.md)
