Performance Testing with JMeter 2.9

Performance testing and tuning

There is a strong relationship between performance testing and tuning, in the sense that one often leads to the other. Often, end-to-end testing unveils system or application bottlenecks that are regarded as incompatible with project target goals. Once those bottlenecks are discovered, the next step for most teams is a series of tuning efforts to make the application perform adequately.

Such efforts normally include but are not limited to:

• Configuring changes in system resources
• Optimizing database queries
• Reducing round trips in application calls; sometimes leading to re-designing and re-architecting problematic modules
• Scaling out application and database server capacity
• Reducing application resource footprint
• Optimizing ...
