Performance Regression Test for v0.4.14

Ensures query params and headers don't cause performance regression

Baseline: v0.4.13 - 180K+ RPS

Target: v0.4.14 - Maintain 180K+ RPS (< 5% regression allowed)

NOTE: These tests are skipped in CI environments as shared CI runners

have unpredictable performance that doesn't reflect actual benchmarks.
