                        Your feedback is important to us. Please share suggestions and feedback on twitter at @whattheperf or Email us at [email protected]
                        Best Practices:
                        Monitor the health of your load generators
                        Monitor all possible infra components and their relations in your application architecture
                        Write down notes about your observations while your test is running
                        Always preserve raw results
                        Decide test duration based on caching in your application architecture
                        Randomize test data
                        Follow good naming conventions in scripts and result files
                        Write useful comments wherever necessary in your scripts
                        Correlate all possible dynamic values
                        Use think time in scripts
                        Modularise your scripts
                        Automate test runs
                        Avoid application changes during tests unless that is the goal
                        Run tests a second time to ensure repeatability and consistency
                        Don't focus on any one measurement
