What strategies did Mr. Mosquera employ to optimize the payment system's response times and throughput?

Mr. Mosquera employed several strategies to optimize the payment system's response times and throughput. He implemented caching mechanisms at various levels, including application-level caching for frequently accessed data and HTTP caching for static content. Database queries were optimized through proper indexing and query tuning. John utilized connection pooling to reduce the overhead of creating new database connections for each request. He implemented asynchronous processing for non-critical operations, allowing the system to handle more concurrent requests. Content delivery networks (CDNs) were used to serve static assets, reducing server load and improving response times for global users. Load balancing was implemented to distribute traffic across multiple servers, preventing any single server from becoming a bottleneck. Additionally, John conducted regular performance profiling to identify and address bottlenecks in the system. Mr. Mosquera optimized the payment system's performance through multi-level caching, database optimization, connection pooling, asynchronous processing, CDN implementation, and load balancing. These strategies significantly improved response times and increased the system's ability to handle high transaction volumes efficiently.
