- Commit: `de046d8`
- Machine: macos/aarch64, 10 hardware threads, Apple M1 Max
- Raw per-cell results: [`index-memory.json`](/engine-assets/benchmarks/index-memory.json)
- RSS is sampled every 20 ms by a background thread for the duration of each merge; every other RSS figure is a single reading in a freshly spawned child.
- Load average is recorded per row: this machine was not idle.| cell | spans | distinct | text MiB | disk MiB | idx MiB (disk) | approx idx MiB | RSS MiB (reopen) | RSS MiB (compacted) | resident/GB text |
