Implement Contract Benchmarking and Performance Report

[famvilianity-eng]

Title: Create Performance Benchmarking Suite and Generate Performance Reports

Description: Document smart contract performance characteristics (gas usage, execution time). Build benchmarking tools that measure and compare performance across versions.

Requirements and Context:

• Measure: deposit, submit_result, cancel_match gas usage
• Benchmark: execution time for 1, 10, 100+ active matches
• Generate reports comparing versions
• Document performance expectations
• Security: Identify performance DoS vectors

Suggested Execution: chore/performance-benchmarking

Implement Changes:

• Create /scripts/benchmark.sh to run contract benchmarks
• Implement benchmark tests in tests/benchmarks.rs
• Generate JSON reports with timing and gas usage
• Create /docs/performance-report.md with results

Test and Commit:

• Run benchmarks on testnet
• Compare against v1.0 baseline
• Document in performance report
• Add performance tracking to CI

Example Commit Message:

chore: add contract performance benchmarking suite

- Implement benchmarking tests for core functions
- Measure gas usage and execution time
- Generate performance reports comparing versions
- Add performance tracking to CI pipeline

Guidelines:

• Establish performance baselines for regression detection
• Alert on >10% performance degradation
• Document expected gas costs for users
• Include performance tips in deployment guide
