## Problem We lack a rust bench for the inmemory layer and delta layer write paths: it is useful to benchmark these components independent of postgres & WAL decoding. Related: https://github.com/neondatabase/neon/issues/8452 ## Summary of changes - Refactor DeltaLayerWriter to avoid carrying a Timeline, so that it can be cleanly tested + benched without a Tenant/Timeline test harness. It only needed the Timeline for building `Layer`, so this can be done in a separate step. - Add `bench_ingest`, which exercises a variety of workload "shapes" (big values, small values, sequential keys, random keys) - Include a small uncontroversial optimization: in `freeze`, only exhaustively walk values to assert ordering relative to end_lsn in debug mode. These benches are limited by drive performance on a lot of machines, but still useful as a local tool for iterating on CPU/memory improvements around this code path.
