5 Best Practices to Avoid a Site Meltdown

Ongoing Simulated and Real User Monitoring
Anticipate change going into a website peak period, and keep testing and monitoring for its impact on performance. Maintain a consistent baseline of clean-room measurements against which to benchmark performance. These measurements provide the guidance to identify issues. Also, augment this monitoring with performance measurements collected from actual user visits. In this respect you have both simulated and real-user monitoring data to provide benchmarks of optimum performance.
