"""Controller perf benchmarks tagged 'benchmark'.

Engine-level benchmarks live in test_performance_benchmarks.py (Task 23).
This file targets the JSON-RPC controller surface end-to-end (HTTP request
→ Odoo dispatch → engine → response). It complements Task 23 by catching
regressions introduced by controller / serialization layers, not just the
underlying engine.
