What Apdex score indicates 'Poor Performance'?

An Apdex score of 0.5 indicates 'Poor Performance' because Apdex is a measurement of user satisfaction based on the response times of applications. The scoring system ranges from 0 to 1, where a higher score signifies better performance.

In the Apdex framework, scores are generally categorized as follows:

• A score above 0.8 usually indicates 'Satisfactory Performance'.

• A score between 0.7 and 0.8 can suggest 'Needs Improvement'.

• Scores below 0.7, particularly 0.5, are seen as 'Poor Performance'.

Thus, a score of 0.5 reflects that the application's performance is significantly below user expectations, leading to dissatisfaction among users. This reinforces the idea that any score falling below the 0.7 threshold is indicative of considerable performance issues, highlighting the importance of constant monitoring and optimization of application response times for ensuring user satisfaction.
