## Problem We don't have any benchmarks for Safekeeper WAL ingestion. ## Summary of changes Add some basic benchmarks for WAL ingestion, specifically for `SafeKeeper::process_msg()` (single append) and `WalAcceptor` (pipelined batch ingestion). Also add some baseline file write benchmarks.
Safekeeper Benchmarks
To run benchmarks:
# All benchmarks.
cargo bench --package safekeeper
# Specific file.
cargo bench --package safekeeper --bench receive_wal
# Specific benchmark.
cargo bench --package safekeeper --bench receive_wal process_msg/fsync=false
# List available benchmarks.
cargo bench --package safekeeper --benches -- --list
Additional charts and statistics are available in target/criterion/report/index.html.
Benchmarks are automatically compared against the previous run. To compare against other runs, see
--baseline and --save-baseline.
