Performance Optimization Checklist
Code Optimization
Review and refactor code to eliminate unnecessary computations and improve algorithm efficiency.
Adopt coding best practices, such as DRY (Don't Repeat Yourself) and KISS (Keep It Simple, Stupid).
Use code profiling tools to identify and optimize performance bottlenecks.
Database Performance
Index commonly queried fields to speed up search operations.
Normalize or denormalize database tables appropriately to balance read and write operations.
Optimize queries by avoiding SELECT * and using query execution plans.
Server and Deployment Optimization
Enable server-side caching mechanisms to reduce database load.
Implement load balancing to distribute traffic evenly across servers.
Compress data and optimize content delivery with techniques like gzip compression and CDNs (Content Delivery Networks).
Frontend Performance
Minimize HTTP requests by bundling files and using sprites for images.
Implement lazy loading for images and asynchronous loading for JavaScript.
Minify and concatenate CSS and JavaScript files to reduce size and number of requests.
Network Performance
Use a reliable and fast DNS provider to reduce domain name resolution time.
Optimize SSL/TLS settings and use HTTP/2 or HTTP/3 for improved performance.
Reduce latency with appropriate geographical server distribution and edge computing solutions.
Testing and Monitoring
Implement automated performance testing in the CI/CD pipeline to catch issues early.
Use real-time monitoring tools to track application performance and user experience.
Regularly analyze performance data and logs to proactively address potential issues.
