3. Making Performance Metrics More Intuitive

Application performance often comes down to a few critical metrics. Here's how to help learners interpret them:

Metric	What It Means	Impact on User
Response Time	Time taken for a page or feature to load	If > 2 seconds, users are likely to abandon the session
Error Rate	% of failed transactions or broken processes	High error rates cause frustration and trust issues
Throughput	Number of user requests handled per second	Low throughput during peak times leads to service delays
Apdex Score	User satisfaction index based on performance thresholds	A low score indicates user dissatisfaction with app speed
