This document provides an overview of performance testing small to medium projects using JMeter. It discusses why performance matters, why JMeter is a good option, how to define test requirements, important metrics to track, and tips for reporting. Performance impacts revenue, user experience, and conversions. JMeter is open source and supports various protocols and integrations. Defining goals, features, and bottlenecks helps shape test plans. Key metrics include response time, throughput, latency and resource usage. Reports should focus on percentiles over averages and use tools like BlazeMeter Sense to visualize data for management.
