Speed up test execution via fabricator optimizations by mroderick · Pull Request #2596 · codebar/planner

Parallel tests with 3 processes: 32% speedup (18.1s vs 26.6s single process). Unix socket had no significant effect. Optimal parallelism is 3 processes for model specs.

Parallel tests with 3 processes: 32% speedup (18.1s vs 26.6s). Full suite ~120s. Pre-existing failures in meeting_spec.rb (not caused by parallel).

Tested 5-6 processes: 5 processes 18.6s, 6 processes 18.7s - both same as 3 processes (18.1s). 3 processes remains optimal.

Final: UNLOGGED tables rake task implemented. Test variance high (87-100s) due to external factors. 2 pre-existing failures.

Final confirmation: 84.4s with UNLOGGED tables. Best result achieved. 992 examples, 2 pre-existing failures.

Documentation update: Session complete. UNLOGGED tables implementation verified. High variance (84-100s+) environment limits further optimization.
