## When to choose Logixlysia

* You want **Pino** performance with Elysia-native `store.logger` ergonomics.
* You need **file logging and rotation** without wiring a separate drain.
* You prefer **incremental context** (`mergeContext`) plus automatic access logs instead of migrating to a wide-event-only API.

## When to consider evlog

* You want a **unified wide-event pipeline** across many frameworks with managed drains (Axiom, etc.).
* You rely heavily on **`evlog/ai`** and **`evlog` auth** integrations out of the box.

## Benchmarks

Run the monorepo benchmark package:

```bash theme={null}
bun run bench
```

The benchmark package has three request-path suites: an **overhead floor** (all sinks disabled — measures plugin dispatch cost only), a **structured sink** run (no-op transport/drain — measures log assembly and dispatch), and a **file sink** run. Compare like with like: the floor numbers contain no logging work by design. Results vary by machine — use them for regression tracking, not absolute rankings.
