MySQL vs PostgreSQL (Round 2) Performance Benchmark (Latency - Throughput - Saturation)

Performance comparison between PostgreSQL and MySQL focusing on latency, throughput, and system resource usage. The benchmark simulates an e-commerce website managing customer and order data, with tests for INSERT, UPDATE, DELETE, and SELECT operations. Improvements include optimized settings for both databases and utilizing i3en EC2 instances. PostgreSQL outperforms MySQL in write-heavy operations, while read operations show smaller differences.
